Ford - Thunderbird :: Misfiring / Engine Struggles To Accelerate
I have a 1995 Ford Thunderbird with the 4.6 V8. I have owned it since it was a year old, it now has 70,000 miles on it. A couple years ago it developed a problem while driving. Hard to explain, but seems like it is misfiring or there a fuel restriction somewhere. This shows up when i floor it, the transmission kicks down and the engine struggles to accelerate, you can feel when it clears up, the car shoots forward. It seems like if i smoothly step on the pedal it is better, but not always.
This problem is also noticeable when the revs are low, like just before the transmission shifts down, like when climbing a hill, you can feel a shudder, if i accelerate and the transmission shifts so the revs are higher the problem goes away. Also, shutting off the overdrive so the revs increase works too. It really feels like the engine to me, although it does not go as far as to backfire.
2 years ago i replaced the auto transmission and torque converter with a factory one direct from Ford.To diagnose what i think is an engine problem i have: replaced the fuel filter (wasn't dirty) removed the injectors and had them cleaned and tested (they were fine) checked the fuel pressure (fine) checked the vacuum (fine) removed the exhaust to look for cat blockages (nice and clean) replaced the plugs, wires, and coils checked that the timing was in spec, although i don't think there is a way to adjust it
The car has the early version of OBDII - it does not have any active errors.
The car starts and idles fine, cold or hot, and when it is not acting up, still has excellent power. It does sit inside all winter though.
Elantra HD (2006-10) :: 2007 - Engine Stalls When Attempt To Start / Place The Car Into Gear (auto)
I have a 07 Elantra with 68,000 miles. I am having a cold start issue. When the car sits overnight and I attempt to start/place the car into gear (auto), the car will stall. This occurs whether the car is placed in forward/reverse and with the a/c on/off. The vehicle will start fine the rest of the day with no issues.

I have a 2006 CTS, 3.6. 128k miles. Always changed the oil myself at 3,000 miles religiously. A few months ago, the car began to "jump" or hesitate when accellerator pushed. Not right away, but after car reached about 30 mph. Again when on it reached about60 mph on highway. It cruises fine, but if you push it, it stutters a bit and the check engine light flashes, Then regains it's composure and away it goes. I noticed that when I changed the oil, the filter is filthy, filthy. Always has been. Use the right oil and all.
Now, I take it to a local national automotive chain and they tell me it is misfiring on #6 and needs plugs, coils and the works. So I had them do it. The car still jumps at same intervals. So i take it back and now it is misfiring on ALL plugs ( or so the computer says). Now the mechanic tells me that the timing chains are all buggered up and the engine needs to be replaced. So I seek another it to another garage and they say that they see the same codes, but don't think it is in need of new engine. They would like to keep it anid see if they can find the problem. A week passes and they can't diagnose the problem.
Engines - Cadillac - Dts :: 2006 - Quick Miss / Just Dies Instantly
Bought my DTS with 46,000 miles, one year ago. I have driven 31,000 miles since. Once in a while, maybe once a month, at 65 or 70 mph it will just hiccup once and keep going. Just one quick miss. About 6 or 8 times in a year it has just died going 30mph or pulling into a driveway or up to stop sign. It does not sputter or miss, simply just dies instantly. So far it has always started right back up. The only code it has ever shown, was mass air flow sensor twice. It looks ok and I did clean it.
View 1 RepliesPassat (B6) :: 2006 2.0T - CEL On And Cylinder 3 Misfiring
My dad has 2006 passat 2.0T. In December 2010 he went overseas. During his absence the car was parked in garage and not in use.
So one day I decided to start the car and as soon as I turned it on the car made this noise and check engine light came on. Took the car to a private repair shop and found out the cylinder #3 was misfiring. The tune up for this car was due so I had all four spark plugs changed and the car ran fine for few days. Then couple of days later it started making the same sound and this time around the coil for cylinder #3 was replaced.
A few days after that check engine light came back and this time it was blinking and the engine was struggling to run, took it again to the workshop yesterday and this time another coil not sure which cylinder was replaced. (all this is done at a private workshop). I have a hunch that the car is going to run fine for a day or so and the problem is going to come back
I never had any major issues with it up until now. Bought this car new in 2006 from dealer. I am afraid that this might be a start of a downhill roll from here on I will drive the car tomorrow and see how it reacts.
Passat (B6) :: 2006 - Car Started Jerking / Misfiring
I've been out of town a bunch and my car has been sitting out at the airport. I picked it up last friday, drove it home. Today on my way to work the car started jerking - like the engine was trying to rev slightly. When I put it in park, and listened, the engine was jerking or misfiring maybe. The exhaust was a bit louder than normal as well and i could hear the stress in it. I also smelt a strange burning smell. I've called and had roadside assistance pick it up and take it to the dealer.

I bought in my 2006 GS300 to Lexus dealer 2 weeks ago for the engine misfire issue and were told to call corporate 'cuz it's over the 9 yr period for 1 month. Called and told me to bring it back for inspection on the issue. Dealer performed the test and found the misfire, but got a call from dealer that they won't cover it because I missed it by 1 month. I had explained to the rep that we moved around quite a bit and found out about this not too long ago.

I have a 2011 Hyundai Accent 1.6L. A few weeks after I bought it w 38,000 miles, it started misfiring so I replaced the spark plugs. It ran great for about another 6 months and started misfiring again. I took it to Hyundai to have it fixed and of course it wouldn't do it for them. I told them what it was doing and they said that there was no code so it was probably my spark plugs. I replaced my plugs with the OE plugs and got the same trouble about 4 months later. Now it has 60,000 miles and my warranty is done. I put in new plugs yesterday and it only ran well until it warmed up and it did the same thing. I ordered new, better than OE Delphi coils yesterday and I'll get them today. I feel like there's a bigger problem with the system that's causing the problem with the coils.

Recently got broadsided (passenger), got the body fixed up. Now it is Misfiring on idle and only on idle...
Prior to this I had Coil go out on me, got that changed out, changed the spark plugs. It was running great then the accident happened an this Misfire on idle problem.
Took it to the shop, had them check for a code, no code. They suggested that it made be do to carbon buildup from the previous misfiring issue and suggested using STP engine treatment on it.
Accent MC (2006-11) :: Misfiring / Intermittently Kind Of Choke
Have a Accent GLS 1.6L, 92,000 miles on it the issue is what I stated above.
Basically back in March I started having issues with my car and it seemed like it was misfiring or something of the sorts at first I thought it was the IAC motor because it would only intermittently kind of "choke" if you will and it only did it while I was idling and in drive. So before I decided to go further with the IAC motor I decided to take it and have the throttle body cleaned, but it eventually started to do it again. After that I had my fuel injectors cleaned and that didn't work much at all. Kept going until a couple months ago when it actually set off a check engine light and it started doing it almost violently.
Check engine light came up with the result that coil 2 is misfiring and I went about replacing the spark plugs and the boot to one of the coils and that made the issue go away no check engine light, no nothing. Past couple days it's been doing it very very occasionally but yet still doing it.
I don't have a whole lot of cash but I need a solution quickly because this is starting to become a pain I don't want it to become so bad that I'm without a vehicle that is operating properly again.
Only thing I can note is that now it is very occasional, and when the car could be otherwise be considered "cold" and often I can't make it repeat the same thing. Had oil above cylinders when I had the plugs replaced.
Accent MC (2006-11) :: Misfiring Followed By CEL Coming On And A Cylinder Cutting Out
I'm having the absolute worst time trying to fix my wife's 09 accent. We bought the car in '12 with 45k miles on it, and just hit 109k last month. About a year ago, the car started misfiring badly (hot day, after reaching operating temperature) followed by the CEL coming on, and a cylinder cutting out. I (mistakenly) figured coils, and replaced them. This "fix" didn't last more than a couple months.
I've also replaced the intake manifold gasket, suspecting a vacuum issue, due to the symptoms. While doing that, I put in a new PCV valve. To no avail, as the car still misses, chugs and shudders while accelerating at operating temperature. I've disconnected/checked the sensors on the manifold, the 02 sensors, the evap purge solenoid...I absolutely can not wrap my head around this.
The weird part is that the car starts fine when cold, (with only a split-second hesitation if you goose the throttle) and will run great for about 10 minutes/until it warms up. Then,once it warms up it will jerk, shudder and not accelerate at all unless you knife the gas. After letting off the gas, it goes right back to "misfiring" and the light comes back on. I can shut the car off, restart it, and it will run fine until the accelerator is pressed.
Sonata NF (2006-10) :: Random Misfiring At Idle And Shaking Really Bad
My car has had random misfiring when at idle and has been shaking really bad but once I accelerate and get up to speed the vibrations and misfiring stop but the check engine light flashes for a few minutes. I have changed spark plugs, all 6 ignition coils the intake manifold gasket and both camshaft position sensors. My car has 180K the codes that are showing up are 300,301,303 and 0016. I really love the car and have had no prior issues the car before this ran like a champ.
View 2 RepliesSubaru - Forester :: 2006 Idling Roughly And 2nd Cylinder Was Misfiring
I have 2006 Subaru Forester that is idling roughly. 90k – oil change every 3k miles. Per diagnostic codes I learned that the 2nd cylinder was misfiring. I replaced the coil, spark plugs, ignition wires, and an airflow sensor. Yet, my car still idles rough. The check engine light is solid and the cruise control is flashing. The idling problem only happens when stopped… after I get high rpms there is no shaking. I had someone disconnect the battery and reset the computer and the lights stayed off for about a week and idling was fine. Week later – the problem returned. I think this an electrical problem, but not sure if mechanical.
View 19 RepliesChrysler - Pacifica :: 2006 - CEL On / Code P0305 Cylinder 5 Misfiring
So my Pacifica, after a long road trip around a year and a half ago, had it's check engine light come on. The meter read P0305, which is cylinder 5 misfire. When I got home, my local trusted mechanic replaced the coil and wire. Since then, the same misfire has occurred at least 4 times, and 3 of which he replaced the same parts (free warranty swap of the parts). The last time, he was determined that it wasn't simply the parts going bad. I concur. It has now lasted roughly a month and the light is back on with the same code. The spans have been as little as a week between leaving the shop and the light coming back on. I personally don't feel the car riding rougher than normal, but my wife does. I don't smell gas, have odd colored exhaust, or any other issue. The only other thing, which idk if it's related, is a clicking noise from the engine, which quickens with revving, perhaps the risers. What else could it be? I read that Chrysler's go to is a valve spring retainer lock and a MAP sensor that accompanies it.

So as I was heading out the other day, the car had low acceleration and engine shaking. The check engine light started flashing.
Checked the codes at the parts store: P0300, P0301, P0303.
I just dropped it off at the auto repair shop.
Could it be a I'm just wondering if I shouldn't have taken it to the dealer as the printout says it could be a CPU issue?
Accent MC (2006-11) :: 2007 - Misfiring Codes P0300 And P0302
My girlfriends 2007 accent as thrown codes p0300 and p0302.
After reading everything I could find, I had coil pack on my list of possible problem items.
The car sat in the driveway yesterday and when she went to start it today, she couldn't get it to.
I got it to start when I got home by giving it some gas while turning the key, but I don't want to drive it anywhere.
The hard start is leading me to believe it's the coil pack.
I was going to start with changing the pcv, spark plugs, and run fuel injector cleaner through it because those are the cheap possibilities...but now may add in a new coil pack.
Accent MC (2006-11) :: 2009 Intermittently Misfiring And Burning A Lot Of Oil On Start Up
So I've been trying to get rid of the check engine light recently so I can get the car inspected. The car has about 130,000 miles. I was having problems with the car intermittently misfiring, and burning a lot of oil on start up. Also the car still had the original timing belt up until this time so I decided to change the valve seals and timing belt. I couldn't get the timing right so I took it to a mechanic and he got the car running like it was before I took it apart, although I don't think he changed the timing between the camshafts. The check engine light stayed on with p0016 as the code. The car accelerated poorly, but otherwise drove fine. I tried changing the camshaft sensor, and cleaning the OCV but that didn't work. So today I looked at the timing between the two camshafts and moved the intake cam over by one tooth which got rid of the p0016 code! Unfortunately the car decided to replace that with the p0340 code. I didn't notice any damage to the pins on the sensor. It seems to stumble for a bit after start, and when releasing the gas after revving the engine, but otherwise idles okay. I have yet to road test it.

Recently my car, after I put fuel into my car, my car won't start unless I apply the gas and then shift it into gear. I thought that perhaps replacing my spark plugs would fix this problem since it is about time for a tune up on my 2010 Hyundai Accent. About a week after changing the spark plugs I now have an error code that states that Cylinder 2 and 4 are misfiring and it is causing my car to shake while it is idling or speeding up. Also it is much slower than before to get it started from a stopped position.
View 11 RepliesChevrolet - Malibu :: 2006 - Misfiring And CEL Started Blinking When Accelerating From Stop Up To 30 - 40 Mph
About a week ago, my wife's Malibu (~130,000 mi) started exhibiting symptoms I would associate with a problem with the ignition system. It was idling rough, it felt like it was misfiring, and the check engine light started blinking when I was accelerating from stop up to 30-40 mph.
The timing was all weird because of the holiday, and so I didn't take it to get the engine codes pulled right away because I figured Id take care of it this week (we were traveling over the weekend).
My wife just called and said her car won't start at all. The car will try to turn over and she didn't describe anything consistent with a dead battery.
If I can't get it somewhere to get the codes pulled, what might be wrong? To summarize, it started idling roughly and maybe misfiring about a week ago, it sat for four or five days, and now it won't start.
Ford F-150 (2004-2008) :: 2006 - Misfiring And Then Stalling When Stopping At Lights
I have an 2006 f-150 King Ranch with 103k miles and it was misfiring and then stalling when stopping at lights. Both cam shaft sensors and all coil packs were relaced then it was still misfiring. The head was recently replaced and now they are waiting on a new computer. When it starts misfiring it vibrates the whole truck and the engine light flashes. If you turn the truck off then back on it will run fine for about 50 miles. Im worried that replacing the computer is not going to fix it, what else could it be?
