Car spits and sputters when engine is cold. When engine is warm car runs fine. I believe that my cold start injector or my cold start injector time switch is bad. 7MGE Toyota Supra ....
View 10 RepliesI have a 2006 Town and Country with the 3.3L V6. The last four times I filled the gas tank the engine spits and sputters after running for 2 - 3 minutes. Sometimes it will even stall out. It will re-start after cranking for 4 - 5 seconds and then runs fine. It only does this right after I fill the tank and doesn't do it again until the next fill up. Thought that I might have water in the tank so I added a bottle of HEET to see if it would cure the problem, no effect at all..
View 4 RepliesTruck spits and sputters when it starts up..and now it does it more often New spark plugs, new fuel pump and filter New mass air flow. I changed fuel octain and that work for a few weeks and back it spits...... It seems that when I put something new in the truck it runs great for a few weeks and then it starts up again...... I can not find a fuel regulator that fits the one that is on the truck now......so I have not replaced it........
View 4 RepliesI've recently replaced the timing chains on my sons 04 F-150 5.4. Now I'm getting a code PO174. I've changed 2 coil packs, fuel filter, MAF sensor and cleaned all the connections. Fuel filter had what looked like brown fuel coming out of the in line of the filter. I'm stressed out now, the truck does not even have enough power to drive up the driveway. Backfires, spits and sputters, has rough idle.
View 4 RepliesMy Honda has a strange problem that is vexing my mechanic. While I am driving, the engine spits and sputters and sometimes dies. I try to restart and it starts right up but runs rough. Sometimes it takes a while to start back up. If I wait a few minutes, it will start again and drive fine for a while. Then it will do it again. After it is warm or when it is cold at the start, it won't do it.My mechanic cannot get it to do it long enough to diagnose. The computer is not throwing any codes. I believe it is electrical because when it does this, the speedometer goes crazy bouncing up and down. Electrical problem also may explain why the computer is not throwing any codes. I need to narrow it down because my mechanic is reluctant to start trying things as I don't have a lot of money to throw at this.
View 4 RepliesI have a 1999 f150 5.4L that will drive normal and all of a sudden it will spit and sputter, the CEL comes on for a second or two, then it’s all over and its back to running normal. I changed the plugs, and fuel filter and it still does it periodically. Vacuum leak?
View 4 RepliesI have a 1999 f250 super duty with the 5.4 Triton motor with a 5 speed. I bought the truck a couple months ago, and it had a bad manifold leak (not surprised lol). but it ran fine just noisy. So i had a shop do new gaskets and bolts. Then my problems started.........
When you start up the truck she runs fine and some times drives fine. I will be driving along and its like some one hits a switch and i suddenly loose all power it spits and sputters and i have to down shift to make any kind of hill.
So I figures I had a misfire i got a light on for cylinder 5. So I decided to change all coils and plugs hoping that would clear things up...... well it didn't. It ran great for roughly 15 miles then it started to do the same thing again. I've changed air filter and fuel filter also.
When it starts sputtering i sometimes get a check engine light on and then it goes away. when the light is on the codes are:
P1151 A Heated Exhaust Oxygen (HO2S) sensor indicating lean at the end of a test is trying to correct for an over-rich condition. The test fails when the fuel control system no longer detects switching for a calibrated amount of time.

Both codes come on together always. but it will go away when the sputtering clears up. I just checked fuel pressure its at 32psi at a idle.
2008 Tundra 5.7 only 55K miles – What is causing an intermittent misfire at startup? It’s been running great, then 2 weeks ago when I started it up I could feel a misfire. By the time I backed out of the driveway the check engine light came on. This is what I have learned so far:
•It only happens when you start the engine and the engine is NOT at operating temperature.
•The engine code always reports misfire on Cylinder #2 I put in a new plug and swapped coils but it still reports the misfire on cylinder #2.
•Once it starts to misfire it will continue to misfire until the engine is at operating temperature and you restart the engine. NOTE: You MUST restart the engine for the misfire to go away. It will be running rough, turn engine off/on once it is at operating temperature and it's as smooth as can be, no more misfire.
•One time I started the truck, I felt the misfire and drove it to a parts store to read the code. Engine was fully warm by the time I reached the parts store. I did not power off the engine, plugged in the tester and read the code which was a misfire on cylinder 2. I cleared the code and within 2-3 seconds it logged the misfire on cylinder #2 again. Cleared the code several times and it kept reporting misfire on cylinder 2. You could also feel the misfire happening. Turned engine off, started it right back up, like before no misfire, cleared the code and it no longer reported a misfire.
•This just started intermittently happening. This morning it happened again, I drove it for about 5 min, engine was about 75% it’s normal operating temperature, powered it off/on, still had the misfire. Once engine temp reached normal temp (about 9 min), I turned off engine, started it back and like before problem was gone.
What is causing this to happen?
I am driving a 1987 mk3 Toyota supra with original engine and transmission. I live in Arizona and it drives perfectly fine in the early morning or late at night, but during the day when temperatures reach past 90°, my rpms will reach up to 5-7000, but won't be gaining speed, thus happens at stops and while driving, my car is an automatic, it does this when I enter 3rd gear.
View 13 RepliesI have a supra that is only running on the first and last cylinder. It was running poor and I pulled off the spark plug wires to see how it ran. After more testing I removed all 4 middle plug wires and it kept running the exact same. What would be causing this? The plugs and wires are new.

Buttery smooth 1st-3rd. 4th does not grind but requires a lot of force to shift. 5th shifts ok, but feels vague; hard to tell it's in gear.
View 13 RepliesI just got back to town with my Supra, 298,000 mi, 7M-GE 3.0L engine. I think I picked up some bad gas on the road. It's acting like I've got dome water in the tank. I've already run a couple of tankfuls. I know the proper way to fix this is to drop the tank and clean it out. But, I can't do that until this weekend, maybe. It's been a couple of decades since I dealt with this. What can I add to the gas to get rid of some of it until I can drop the tank?

Two days ago while doing a routine oil change I noticed my kids engine compartment was real dirty as we had alot of flooding from rain a few weeks ago. I sprayed the engine with a water hose w/nozzle to clean it. At the time I didn't know any better. The car was driven without any issue briefly that day. The following morning the car was driven a distance of 25 miles without incident.
After resting 30 minutes the car was started and began to idle rough and stalled repeatedly. When I showed up to inspect the issue it had been sitting about an hour. I went for a test drive and the car ran good. About 20 minutes later iI get another call saying the car is doing it again. It was sputtering/ hesitating when I attempted to accelerate it began to stall unless I limped it along staying off the gas.
Once I got it home I started doing some research and discovered that my spraying water in the engine compartment was probably what caused the issues I was experiencing. So I began to go through the motions trying to repair. I also noticed the car ran good when cold but at operating temp it would run rough. The check engine light has not come on.
I replaced the spark plugs, plug wires, distributor cap & rotor, etc... sensor, and air filter, I cleaned the throttle body port and IAC valve port with sea foam cleaner. I cleaned and tested the EGR valve & ports. Nothing has improved from my efforts.
I must of screwed something up good, since its been 2 days, it should be dry by now. I also been thinking that maybe some water got to the injectors. NOt sure if a cause, but the oil was changed right before I sprayed engine.
My course of action as of right now is.
1.Check and clean all electrical connectors
2.Replace distributor with a re-manufactured one
3.Replace upstream o2 sensor
I have a 1997 explorer sport 4x4 4.0 sohc It has a real tuff time with cold starts sputters won't hold and idle sits at about 500 rpm once its warm its not as bad still has a low idle.
Also i have a constant engine rattle thinking left front cam tension-er
Also throwing and check engine light odb scan tool shows o2 sensor position two is bad
I was thinking intake gaskets and new tension-er is a good place to start.
I have about 140,000 miles on my car, a 2006 Toyota Prius that misfires at idle when cold, and for the last 10,000 miles the engine has been using between 1 and 2 quarts of castrol synthetic 5w30 oil between the 5,000 mile oil changes. My check engine light naturally stays on constantly now and the engine also appears to misfire on acceleration also.
For the first 60,000 miles I had the oil changed at various places every 3,000 miles using nonsynthetic oil that was recommended in the car manual. Since then I have been getting the oil changed at the dealer where I bought it new and they switched to the synthetic oil, so I asked the service department, why the misfire? They said the new type spark plugs are very sensitive to oil burned in the firing chamber, causing the misfire. They told me to check the oil often which I do and the engine has never been more than a quart low.
Is there a spark plug I can use that is not as sensitive to the oil, or should I be looking for a junk yard engine or is it cheaper to have my engine taken apart and repaired. Will it damage the engine further to keep running it, there does not appear to be any smoke coming from the tailpipe.
From new I got mpg in the 40's now I am getting 33 to 34 mpg.
I have recently purchased a 2012 facelift Tiguan diesel and it has a running fault. When starting the engine, 50% of the time it starts fine, 50% of the time it starts with a "misfire" and sputters for a short while (5-6 seconds) then stalls. If you Rev it a bit while it is sputtering then it clears the sputter and doesn't stall. It doesn't matter if it's hot or cold. Once it's running fine then the misfire never returns until you shut off the engine and then try to restart. The start stop also fails to cut in and I'm wondering if this could be linked. It had a new battery and alternator fitted a few months ago but a non start stop battery was fitted. This has now been changed for the correct battery but both problems still persist.
View 2 RepliesMy car is misfiring, as in acceleration 90% sputters until I lay the pedal to the ground, which obviously isn't good for my gas. What do I do? I can't find anything online and I don't want to be throwing money into things that don't work.

Backstory. The P0411 code shes had for quite some time. I think probably 4 years maybe. Just never did anything about it because I guess they are expensive to fix. Thats the SAIP and combi valve correct? Anyway to remove all the emissions stuff and get the codes deleted?
So, about 3 weeks ago, maybe a little longer i cleaned her engine bay, replaced a few vacuum lines because the shop she took it to last year did a terrible job. Mind you, they did a head gasket, timing belt and some other minor things while they were in there. And they couldn't take the time you run new vacuum lines, since they just cut the originals and used a bunch of t fittings to "solve" the problem.
Anyway, i replaced the lines and it seemed to run better at idle, still had a little mis at idle but ran smooth at speed. I also did an oil change, put some fuel injector cleaner in it, put some seafoam in the oil, and cleaned the engine bay thoroughly. I did it properly and took all the plastics off, cleaned them, scrubbed the bay and used an air hose to get rid of the excess water. Left in a nice state. Ran smoother, looked better, so on and so forth.
Fast forward to last week, and she mentions to me her car isnt running right. Its sputtering, hesitates, running rough, exhaust is puttering, and it used up a lot of gas. She parked it for a few days, and i came down to look at it. Mind you, i don't have a code reader. So I looked at it blindly thinking it had an ignition issue. Nothing could have changed that quick since i looked at it.
So, today we got one coil(just in case ones bad), and 4 new plugs (Autolite Iridiums). Replaced and gaped the plugs to .030, torqued to 23 ft/lbs and started the car. Seemed to run a bit better, but subsided quickly. I then pulled each coil harness plug to make sure it would misfire on each cylinder and it did. So, new plugs and the coils checked out. Time to get its codes read.
Took it to the Pepboys and the codes it came back with were the P0011, P300, P0301-3. Cleared the codes and they came back nearly immediately. I had the dreaded P0011 code. The misfire codes im guessing were from the coils being pulled on each one, and also due to the P0011. Now i read a lot of threads about the P0011 and how its usually not the camshaft position sensor. However, i pulled the plug on that while the car was running and nothing changed. So i thought it could be the CPS. Changed that out and still nothing.....
I have a 01 f-150, 4.6L, with 160k miles on it. Symptoms: It idles fine with an occasional surge. It sputters in all gears like a misfire (all plugs and COPS replaced 2 months ago). Sometimes it stalls out going down highway or as I turn in my driveway. It also seems like its slipping a little without the "hard jerking into gear". Occasionally the rpm meter will peg low and then return to normal.
The only code that I received was P1451. I changed the canister vent solenoid but the symptoms remain. I've checked voltage on the TPS (the variable voltage checked out but I didn't get the 5V ref. voltage). I've cleaned the MAF sensor. I've also changed the fuel filter. I've resistance checked the connector to the PCM and found several pins that are at ground. I'm not sure what to do next.
