Well, I just went to grab some lunch and on the way home I got on it a bit. I was met with sluggish acceleration and a flashing CEL. Before I could even turn the car off, the CEL went away. I was about 200 yards from my house so I coasted home. What could the issue be?

I started noticing a little stutter when trying to hold 45 mph if I hit a mild incline, and also at 70 or so if i hit an incline.
Around the same time, I noticed that acceleration seemed sluggish when getting on the interstate. Gas mileage dropped from 16-17 mpg combined to 12-13 mpg combined.
Historically, since I bought the truck 3 years ago, if I go WOT to get up to highway speed (Not my normal mode of driving, more of a test) I would get a misfire on cylinder 8.
About 2 weeks ago, driving around town, I got a check engine light. The code said it was rich on bank 2. Cleared the code, it has not come back.
Here is what I have done:
Flushed the tranny (Vehicle history shows this has been done consistently since original purchase)
Changed all 8 plugs (none broke!) and all 8 COPs. - Fixed the misfire on cylinder 8.
Still sluggish and still have the stutter at 45 and 70 on an incline. I know it's not a racecar, but 0-60 in 19.6 seconds seems quite unreasonable.
New Fuel Filter
New Air filter
Cleaned MAF sensor
Had the back pressure on exhaust checked. No blockage there.
My torque app tells me the TPS is functioning normally.
No codes are being thrown, no CEL at this time.
What am I missing? I have a reader that will chart up to 8 sensors as I drive.
Triton 4.6, new air filter, throttle body cleaned, new fuel filter. Seems sluggish off idle, and when I let off accelerator, rpm's take a few seconds to come down. If the truck is setting still, a quick hit on the throttle takes a second for the engine to build rpm's.
View 10 RepliesThe check engine light is on, all the gear indicator lights are on and acceleration is sluggish. I'm taking it to the dealership tomorrow, but wanted to know where I stood before talking to them. I don't really trust them. Transmission? Gear shifter?
View 2 RepliesI drive a 2001 Hyundai Accent. About a month a go the CE light came on. at first, the car was driving fine so I thought nothing of it. Then I started noticing that the acceleration was sluggish and when it finally accelerated, it basically slingshot forward. What could be wrong. There's no smell, rattling or anything else. The only thing I noticed was the engine was a bit louder.
View 1 RepliesI recently took my truck to the mechanic for a bad transmission leak, they told me they had to replace the Oil Cooler Lines (upper and lower) and that they did a transmission service (flushed out the transmission), the leak is fixed, but as soon as I started driving, I noticed that the acceleration is very sluggish from a full stop, I can floor the pedal and there is no difference, once I get going it seems fine (though a bit high on RPM's but not much). I also noticed some of that liquid sealant residue droplets on my windshield, similar to the type of sealant an AC place did for me to seal an AC leak, not sure if that has anything to do with this.
View 8 RepliesI picked up my first GTI about 3 months ago, a 2011 Autobahn with about 35,000 miles. I love the way it drives. I had been admiring them from a distance, and was finally able to pick one up. Unfortunately, I've run into a few issues. I'm pretty much a rookie when it comes to the inner workings of cars, but I'm eager to get into it more. My issue is below:
Over the last few weeks, the car has been consistently a little sluggish, and the acceleration has seemed a bit jumpy. I've only used premium gas, and I've been looking for simple things that might be the issue. I live in Houston, and I was wondering if maybe the extreme heat and humidity might be the reason behind the sluggish performance.
Yesterday, I decided I would clean the air intake filter. It has a K&N intake from the previous owner. After cleaning the filter and replacing it, the car wouldn't start. I may have put too much oil on the filter or the humidity may have just caused it to take longer to dry than the instructions on the cleaning kit recommend.
I called my bro-in-law who is the go-to car guy in our family. He recommended that I try starting the engine without the air filter and pull out the MAF sensor and check it out. When I took off the filter, the car started fine. I replaced the filter, then also pulled the MAF sensor to see if it needed to be cleaned. I found that the bottom of the MAF sensor was bent and slightly dented. I could also see a place where the sensor had scratched the bottom of the pipe.
This morning, the car is running a little smoother (better than before, but not as quick as I remember), but the check engine light has come one. Could the performance issues be due to the damage to the MAF sensor? With the check engine light, is that something that is automatically triggered by removing the MAF sensor? Or is there some other issue.
I have a 96 aurora that has been giving me alot of problems. It started with the car being real hard to start and very sluggish upon acceleration. I had an engine code of 0300 (multiple cylinder misfire) I had a full tune up as well as an intake manifold gasket done. This seemed to fix the problem for a short time. The problem then started again. this time i was told that it was a fuel pump so i went ahead and changed that as well. Again this fixed the problems for a short time. Now i am having the same problem again. I now have 2 engine codes 0300 as well as 0151(bank 1 sensor 2 o2 sensor) This started after it rained and i notice the problem always seems to be a little worse when its wet out. Also the car is really only hard to start when it has sat for awhile. m If i drive it and come back 5 minutes later it will start right up though it still idels really rough and has no acceleration. Can the o2 sensor be causing the misfires and if so will that make it hard to start. Also if i changed the fuel pressure regulator about a year ago.
View 2 RepliesLately I have found that when I am trying to go up an incline on my road, that my car has trouble accelerating. Almost as if the engine is being choked off like it is about to stall or is out of gas. I have to press the accelerator almost to the floor to get up the incline. The suddenly it will lurch and accelerate rapidly as if I have put the car in Power Mode.
I should also add that this only happens when the engine is cold. I didn't have this problem last year at all. I usually wait a couple of minutes after the engine starts before I try to drive, but that doesn't seem to work.
Experienced sluggish acceleration with their "09" Santa Fe. I have the 2.7 liter 6 cyl. engine and it seems so sluggish when accelerating. I have replaced all the plugs with some best rated ones specific to my model. I have tried one of the best rated fuel system cleaners. It still seems to have no pep, my daughter's 1999 Honda has far more get up and go.
View 7 RepliesI was on my way home suddenly the acceleration of the trib went sluggish.... low idle especially when you put it on drive and with the a/c on. It can rev but it feels like you are revving a 1.1L engine.
What could be the cause? I already had the sensors etc cleaned 6 months ago.....It has NO check engine light.
I have an 08 460 LS. I am experiencing sluggish acceleration. It feels like the car is in the wrong gear and has no power. This is intermittent and most of the time ok. Occasionally it is jerky when pulling out when it has proper power.
View 6 RepliesI have encountered a problem with my car engine. I noticed the car was not putting out enough power. When I press on the gas pedal aka accelerator the car drives real slow or sluggish; it seems like there's something clogged. I recently replaced the alternator which was draining the car battery. Since then the car starts up without any problem. I assumed its the EGR valve. The original EGR valve was quite carboned up but the used one from the junk yard didn't do much justice to the problem.
Additionally, the car is rough idling which I believe was due to bad gasoline.
Catalytic converter was struck by curb and heat shield was damage. Everything seems to be intact!

I have a 2007 Mazda 5 and over the past few days, I notice the acceleration seems slightly sluggish, especially on inclines. Then last night I had a problem where I was driving and whenever I took my foot off the accelerator, the car would stop (rather than gradually slowing). And when I put my foot back on the accelerator, the car jerked forward before finding the right speed. I parked and after work, it drove just fine. Drove fine this morning also. The shop says I need a new solenoid purge valve, but after reading about that valve, I don't understand how it could cause my problem. The car didn't stall whom it stopped, it just stopped moving forward.
View 4 RepliesI am having some trouble with my 02 Buick recently. The acceleration from a stop is very sluggish and gear changes come slowly, although they still seem to shift smoothly. The first thing I did was check the fluid levels and I can find nothing wrong there. The trans fluid was last changed 3 years ago, but the level, color, and smell are all normal so surely that couldn't be the culprit ?Unfortunately, that about exhausts my diagnostic skill.
View 8 RepliesI have a 2004 Prius, ~150k miles. At about 80k I replaced the inverter coolant pump as a preventative measure.
Recently, the car has shown an intermittent lack of power, and abnormally sluggish acceleration, which seems similar to what I've heard about the failsafe mode of an overheating inverter, except no warning lights appear. We have had some hot days this summer in SLC, Utah (100+ deg). It's a sporatic issue that seems much worse on hot days. The weather has been hot, but we've had hot days in past years and not had this problem.
Yesterday, the car showed the worst ever such behavior and was nearly crippled for my wife (why do these things always happen when the wife is driving alone?). She was returning home from a ~ 1hr appointment, where the car was parked in the sun, ambient air temp was ~103 deg. The car was very sluggish and ICE was revving much higher than normal. The battery fan that vents next to the rear passenger-side door was running at the higher speed than she's ever heard it before. I asked her at the time about the battery level, and the display showed two bars, even though she was going mostly downhill. A/C seemed to be working, but she turned it off. She was able to limp home. It did seem that when the battery charged a bit, performance improved somewhat.
After I got home a few hours later that evening, (temp ~90-95 deg), I took it for a spin and it seemed fine. I'm pretty sure I detected a slight hiccup in power one of the times I punched it, but nothing drastic. She drove it this morning (84 deg ambient, ~75 deg overnight low) and it seemed normal, except that she could hear the battery fan (we almost never hear it running), but it was much slower than yesterday.
2004 Santa Fe 2.7L V6 2WD ... Car was running fine, filled it with gas, and upon starting, heard a backfire into the intake manifold. It coded for a Cylinder 3 misfire so I had plugs and wires changed.
Now...The car starts, idles rough, accelerates sluggishly, and running rough any time it was around 2000 RPM. After I changed the plugs, it started bucking a little and stalls when I take off in the morning.
Coded and it's reading 7 codes, but some are duplicates:
-P0274 Cylinder 5 Injector Control High
-P0305 Cylinder 5 Misfire
-P0102 MAF or VAF A Circuit Low Input
-P0050 H02S Bank 2 Sen 1 Heater Circuit
-P0030 HO2S Bank 1 Sen 1 Heater Circuit
-P0274 Cylinder 5 Injector Control High (Shows Twice)
-P0102 MAF or VAF A Circuit Low Input (Shows Twice)
After having a backfire and then cylinder misfire...replacing the plugs and wires.
1991 Acura Legend 6 cylinders
For about a week, my car was hard to start, and very sluggish upon acceleration. By Friday, the car was not getting over 20 mph, chugging, and semi-backfiring. I took off the valve covers and found quite a bit of oil in the 2nd cylinder, along with a crude covered ignition coil. I replaced all 6 spark plugs (properly gapped) and bought a new coil for the #2 cylinder. I also replaced the valve cover gaskets, and all 6 rings to prevent more oil seepage. After putting everything back together, making sure wires were correctly aligned, the car will not start. It cranks, but does not turn over. I put the old coil back on, and it did the same thing- crank but no start. Have I lost compression? How can I restore compression? The engine sounds so close to turning over, but not quite there. I'm stumped.
Car Details : 2004 Mazda 6 V6 3.0 L engine automatic transmission with 88,000 miles
Car Problem Vignette : After driving for a bit, say 20-30 mins (after my engine gets hot), I start to smell a burning oil smell. I’ve looked under the hood at my engine and do notice some oil leaking from the engine. This is not just some simple oil leaking after an oil change. The oil appears to be coming out of the engine "seams" itself. This has persisted for some time now. This problem started at least a year and a half ago now (12/05/12). I’ve had a mechanic take a look at the oil leak and supposedly he fixed the head gasket or valve cover gasket (I’m not sure which one), but the problem never fully resolved.
In a related or unrelated situation (I’m not sure yet if it is related) during this time my car started to jerk and sputter when I drove, so much so that I wasn’t sure it was going to make it to work one morning. The check engine light came on and I eventually made it to work and back home that day. It gave me a code that said one of my cylinders was misfiring. I proceeded to change all of my spark plugs to no avail. I then changed out one of my ignition coils to the bad cylinder misfire. It fixed my problems with the stuttering and I could drive my car again without fear of stalling. However, I still smelled burning oil. Over time I eventually started to feel my car struggle to take off during acceleration which felt different from when my car seemed like it was going to jerk and sputter to a stall. During this time frame one day I was at a stop light and when I went to take off, a huge plume of bluish / white smoke came out the exhaust and I smoke-screened the people behind me. After that incident, I ended up changing my positive crankcase valve (PCV). After changing my PCV my car felt like brand-new again! I could not believe it! My car started accelerating smoothly and driving so much better. I felt like I had gotten the “Zoom Zoom” back for my Mazda.
Sadly this didn’t last long, maybe a month at the most. My car started struggling during acceleration again and I started smelling burning oil again. I have dealt with this for over a year now. My car still runs and gets me around, but I can’t remember the last time that my car ran smoothly or didn’t smell like burning oil except for that time I changed the PCV. I have never seen any kind of smoke coming out of my exhaust again like that one experience.
Problems:
•Burning oil smell coming from my engine due to leaking oil coming out the "seams" of the engine
•Car is struggling when accelerating especially at lower gears
•I feel it every so often when I accelerate somewhere between 2nd and 3rd gear that the car jerks and makes this “chunk” type sound and feeling when it shifts gears.
Questions:What is wrong with my car? Are all these situations related? And what do I need to do to stop the oil leak and acceleration problem?
I recently replaced the 181K mile valve-burned engine in my 2001 Honda CR-V with a 40K mile engine from Japan. Since the swap idle is slightly erratic, acceleration from a stop is sluggish and check engine light indicates "P1508 error code" which is "Idle Air Control valve circuit failure." Also have an issue with the A/C cycling on and off rapidly when idling that goes away as soon as the engine rpm is slightly increased. New OEM IAC valve is costly so I hesitate to replace it. All parts other than the engine itself are from my original engine in my CR-V.
View 3 RepliesWhat is a "normal" number people see on their load factor? Mine was around 25-30 a few weeks ago but I noticed it is increasing to around 30-40 once I'm in gear, in park it's fine. My acceleration is also getting a bit sluggish too especially going up hills and my throttle isn't responding all the way, my turbo boost is normal though and I don't think there is any VGT stiction. I'm thinking either a fuel filter or a MAF sensor to start with. Fuel filters have been in exactly 10 months. Can a dirty fuel filter, air filter, or MAF sensor affect engine load at idle and how fast it accelerates? I feel like I'm pulling a trailer and with it being more sluggish, my transmission is shifting harder as well.
