Caravan/Voyager :: 1996 Van Started Chugging - Random Misfire / Bad Cylinder
Last week, my van started chugging and the keydance code indicated random misfire. I changed the front spark plugs and wires and it ran a little better but still showed the error. Took it to my trusted mechanic and he changed the back 3 wires and plugs and the coil pack. Code now showed misfire on one of the back cylinders(I forgot which one). 2 Mechanics both confirmed good spark and gas at the cylinder. He is saying that there is a mechanical problem in the cylinder and the fix would be over $1k.
The van has over 250k on it so it's not worth the engine work. I asked about a compression test and was told that it's almost impossible to test the rear cylinders without doing a ton of work, and that they are 95% sure that it is a mechanical problem with the cylinder. I've known the mechanic for over 20 years and he is an honest guy, and knows that I won't do the expensive repair, so he's not trying to rip me off.
I don't have the facilities or knowledge to do the work, so it looks like I'm screwed. Is there anything else that I should be doing before I write the van off? It does run, but very rough at low speed, and no power at high speed, and mech says that the unburned gas will eventually screw things up.
Caravan/Voyager :: 2002 - Check Engine Light On / Intermittent Misfire
I have an 02 Dodge Caravan 3.3 L Flex . It had initially stalled and wouldn't start. Check engine light was on. Had it towed to a Cert Mech. He said it needed a "Major" tune-up. I let him do this. It included: New Coilpak, plugs, plug wires, cam-sensor, crank sensor. That's what was on 1st invoice.
It started, but was still running very rough. He then recommend a new PCM. After choking on his estimate, and paying the initial invoice, I decided to let someone else have at it. Mech # 2 installed a "Rebuilt" PCM, New Battery, and a PCV Valve.
It runs good now BUT, ...It has this weird idle Misfire. The only time it happens is at a stop light when at idle. And it doesnt do it all the time. This check engine light is not on... At this point, all I want to do is sell it.I have over 1K in repair costs and still can't get rid of this misfire.

My check engine light came on today and while driving, the idle (RPM's) were very high. At about 80KMs, it was about 3500 and when I accelerated, the engine would race along with the RPMs. While stopped, idling seems fine. I couldn't get over 80KMs/Hr without the idle going too high.
What it could be? Haven't had time to check codes as it is long weekend and garages are now closed till tuesday.
Caravan/Voyager :: No Speedometer / Wouldn't Shift And Check Engine Light Came On
I was able to quickly diagnose the problem with our 99 T&C LXi w/3.8L.
Problem: No speedometer, wouldn't shift, check engine light came on.
Many posts suggested speed sensor. There are actually 2 of them. An input and an output. Both cost approx $20 each.
By removing the aircleaner box assembly, I had the best (relative word) access to the sensors. A 1" socket w/3" extension did the trick. I understand the access for 2000+ models is different.
Corolla :: 2011 - Check Engine Light On / Random Misfire
I have a 2001 corolla with 37K mi on it. The check engine light came on today. Took it to advance auto parts to read the code. It showed P0171 (System too Lean) and P0300 (Random Misfire). Called up a toyota dealer and the technician think it might be bad gas. I buy gas at name brand gas stations and sometimes from BJs. I am not sure if the problem is with gas. I also been up to date with maintenance.

Just bought 2007 Gs 350 in Dec 2015 with 60k miles. The other day I filled up with gas and drove to work. On the way home check engine light started blinking, check VSC appeared on display screen and traction light came on, car ran rough, and wouldn't accelerate. Got home and searched the net.. So I removed gas cap... No change.. Then removed neg battery cable for 10 min. Fixed problem for about 10 min. Then it all happened again. Next morning took it to Lexus dealer. The rep called and said it gave misfire cylinder 3. They said they checked valve springs and they are good, exchanged coil pack with different cylinder and still misfire #3. He said has to be injector so they want to replace injector ....
View 8 RepliesDodge - Neon :: 1997 - Check Engine Light Has Been On And Causing Random Misfire
I have a 1997 Dodge Neon with about 153,XXX miles on it. My check engine light has been on and i know that is caused by a random misfire. But more recently i went to start my car and it started but ran for less then 10 seconds and died. I tried to start it again and it wanted to but wouldnt make the final step i guess. We checked my spark plugs and i had oil sitting in 3 of the 4 there are. We have tried starting it again after cleaning the oil out and it started on the first try, I am just afraid of messing anything else up so until we figure out why it did this to begin with the vehicle is off limits. My Fiance said we need to replace the spark plugs and a gasket.
View 4 RepliesGolf IV / Jetta IV :: Check Engine Light Blinking And Sputtering On Idle - Misfire?
On my way to work, my check engine light started blinking and car was sputtering (real bad on idle). I ran the code and it came back with misfires codes. I changed the coils/plugs, fuel filter and fuel pump last year. Can the coils be bad already? When I clear the codes the car will run fine for a little while. But after a couple miles CEL will blink and the car will run roughly again.
Car : 2004 Golf 2.0
Codes:
16684: random multiple misfires

Question is what will be causing this to happen. I thought about changing the spark plugs to see if this is possibly the cause. but what else should i be checking?
View 1 RepliesSonata NF (2006-10) :: Random Misfire Code P0300 - Check Engine Light Flashing
I know it is a random cylinder misfire code however I started my car in the morning and it was fine I moved it and put it back in my driveway. I started it up later and waited for it to heat up i came back outside 10 min later and my check engine light was flashing and my car was shaking like crazy you could tell the engine was misfiring like crazy. I had under a quarter of a tank but not empty yet. I shut it off and turned it back on and it was still doing it. I drove the mile to the gas station the way it was.
Under partial throttle it was revving to 4500 and over 5, had to let of throttle to make the car shift up a gear. I filled up and started the car again performed fine after that however the check engine light was solid now and still on. I went to my local mechanic and he read that code P0300. I changed my spark plugs that day and they were crap the original spark plugs I have 65,xxx on my car now. Car is smooth now. I cleared check engine when i saw him first and it did not come back on all day even before i changed the spark plugs later that night. Why my light was flashing and why my car was acting like that till i filled up?
Elantra XD (2001-06) :: Check Engine Light Will Pop On Occasionally And Code Reads Random Misfire
2004 Elantra AT ... 6 months ago top of the radiator cracked caused it to overheat and blow the head gasket and warp the head. Repaired that and compression is fine now. It ran great for 4 months but now it randomly stalls. at or near idle. Seems to do it more at operating temp rather then cold. Occasionally the check engine light will pop on and the code reads (random misfire). It acts just like it has been shut off. But immediately restarts.

So last Thursday I started my car up in the blistering cold and it ran fine for about a minute and started to misfire so I shut it off. It hasn't ran since. When that happened the check engine light was blinking because of the misfire. I didn't have a code reader at the time to read it. now that I got a code reader the damn thing isn't throwing any codes. it spits and sputters sometimes. I've had no previous problems with the car. Thinking It might be a weak fuel pump or bad coils and in not sure how to test them.
View 1 RepliesFord - Windstar :: 2001 Misfire Occurring - Blinking Check Engine Light While Trying To Accelerate
I have a 2001 Ford Windstar Sports SE with 155K miles. I did a tune-up eight months ago. With the tune up I had to replace the fuel pump because it was defective. Later, I found that there were misfires occurring since I was getting slow acceleration. I had the spark plugs on the guilty cylinders replaced again and the spark plug wires.
Periodically, I have had to return to the shop to have the vehicle checked. I sometimes get a blinking check engine light while trying to accelerate, which now occurs only while it is raining or I am exiting the car wash. The shop is at a loss as to what it is (spark plugs and wires are fine, no lose connections noticed). I am wondering if I should take it to someone else. Of course, taking it somewhere else will cost me $100 to check on someone's else work.
The shop replaced the ignition coil. Distributor cap is fine. They keep saying that the engine is running fine while in the shop and do not get any codes. I had them drive it while it was raining and they discovered that cylinder 4 is misfiring. They worked on the cylinder. The vehicle runs well, until it rains or I wash it.
My questions to the group, "If everything is OK, how come it is misfiring? What are they missing? What is the connection to the moisture?"

View 2 RepliesFord Ranger / B-Series :: Check Engine Light Started Blinking On And Off - Code 327 / 328 And 334
I've got a 1992 Ford Ranger 2.3L with about 240,000 miles on it. The check engine light started blinking on and off pretty regularly so I pulled the OBD1 continuous memory codes and came up with this.
327 - EVP/EPT circuit below minimum voltage
328 - EGR closed valve voltage lower than expected
334 - EGR closed valve voltage high
I can't say these codes mean a whole lot to me besides I've got issues with my EGR valve and possibly the EGR valve position sensor. I was thinking I'd start by replacing the EGR valve.
Pontiac - Grandam :: Shaking / Check Engine Light Came On And Started Blinking - No Compression In Cylinder
About a week ago I was driving my Pontiac 2003 Grand Am V6 and it began to violently shake and the "check engine light" came on and started blinking. I then immediately took it to the mechanic It has been with the mechanic for 6 days and they were unable to locate the problem. They called me today and I was told that I have no compression in one of the cylinders (I have done business with them before and felt comfortable in that I wasn't being taken advantage of). Also, is there any problems in the future with getting a cylinder replaced i.e. other parts of the engine that might correlate?
View 17 RepliesImpreza :: 2000 2.5RS Misfire - Check Engine Light Came On Again And Started Flashing
I've got a problem with a 2000 Impreza 2.5RS 5spd. It started with the check engine light coming on. A trip to Auto zone revealed that the O2 sensor was the problem. But on the way home, the light came on again and started flashing. All the while the car started acting like it had a misfire. It idles really rough and the exhaust smells like it's running really rich. I've replaced the plugs and wires, and all corners of the ignition coil check out properly as well. Can the O2 sensor cause a misfire in one or more of the cylinders? Or is something else that I should be interrogating as the cause?
