Aug 29, 2014
I have a 1996 chevy caprice wit a 4.3 v-8 one day i was driving and the car started acting funny and the check engine lite started blinking i had the codes read and 0p300 came up saying multiple misfire so I changed the plug wires they all connect in the front around the harmonic balancer well that didn't work its still saying multi misfire so I took a spark plug wire off of the electric dis block and no change in motor now I don't know what to do...

I have a 96 Grand Voyager that had had sat for a year undriven or started due to being out of state. It ran like a champ when I parked it. Now I charged the battery and went for a drive on the freeway and my check engine light came on and started blinking. I had the code read it came back with 2 codes a P0306 and a P0300. I noticed that the cylinder 6 spark plug wire was arcing on the core support. So I replaced all the plug wires and spark plugs with Champion platinum spark plugs. I cleared the codes and took it on a test drive and the P0300 code came back. Is there anyway the old gas is causing the random misfire? or what else could it be?

The problem that causes the check engine light to come on cannot be traced. The diagnosis is multi engine misfire. The dealer has checked and recheckedbut problem still exists. The last time my mechanic changed spark plugs he noticed oil on one of the plugs he removed in the rear side of the engine. He replaced the plug with the rest of them. Could it be that one or more of the spark plugs are sucking oil and causes the misfire? If so what could be the cause of that. Do I need a full tuneup? My dealer recommends replacing the cam shaft pulley because it's loose and this may or may not solve the problem. I'm not a mechanic but it appears as if the problem has something to do with the spark plugs sucking oil since the check engine light might go ou for a week or so and then come back on for a while. Lastly is it dangerous to keep driving the car especially on long trips?

I have a 2006 F150 4x4 5.4. For a long time it idled poorly and would take 2 trys to start. Today it started shuddering and the engine light came on. The engine light went off but it still runs rough and smells of gas from the exhaust. It is not very drivable and I can't afford to take it in. I have lots of mechanical experience but not with this electronic junk and need diagnosing the problem. I have a code tester and this is what it said.

P0304 Cyl 4 Miss

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 ....

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
16648: fuel injector #2 short to ground

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.

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?"

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.

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?

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?

1997 Ford F150 - 133K Miles - 6cyl - 4.2L. This is a truck that gets less than 2K/year put on it. Has had "issues" with worn bearings and holding oil pressure for a few years now. Yesterday, the check engine light started flashing (as opposed to solidly lit) and the code came back as a cylinder #4 misfire (only the one code). The truck was clearly not firing on all cylinders and at idle, ran terribly (couldn't be driven). I just did a compression test on all the cylinders and all measured around 140-145psi except the #4 which read almost 170psi. I rechecked this a few times as well as a couple of the others and am now sure of the results. What could cause this one cylinder to have a higher compression ? Is whatever is causing this increase in the compression, also be the cause of them misfire ?? I'm stumped here and quite frankly, expected the compression on the #4 cylinder to be really low as opposed to the others.

My daughter has a 2003 Passat Turbo. Two weeks ago it started to run like crap with a check engine light on. I pulled the codes and it said multiple misfires. My buddy owns his own shop and said bring it down. He pulled the plugs and the spark plug holes were filled with oil. He changed the valve cover gaskets and replaced the plugs. Still ran rough with low fuel pressure so he replace the fuel pump and injectors. Still runs rough, when he pulled the air intake off there was oil in it. Could this have happened do to the valve cover gasket? The codes still read misfires. He said the turbo was full of oil also. Could the turbo be bad causing it to run like crap? Can it be rebuilt? I really don't want to go to the dealer.

I have a 2011 I4 camry. I recently ran out of gas and decided to keep trying to see maybe if the car would turn on. After all that i gave up cranking the car on and decided to push to a gas station. After putting in gas (93 octane) I realized i have my check engine light on and another light which depicts a car with 2 swiggly lines.What that light means but its to the right of of lcd display which shows your mileage. I am taking the car tomorrow to the dealership but I was wondering is there any way i can check the codes without an obd scanner (the thing that checks for codes). Do you think I ruined my engine after trying to start the car multiple times without gas?

My check engine came on last night and stayed on during multiple restarts and also again this morning when I started it. I thought I was ready to bring to the dealer Monday morning but the light "magically" went off while driving today. What could cause this? And finally would there be a code stored that the dealer could check?

The engine light in my 2001 Passat all of a sudden started blinking when I started it this afternoon - for no apparent reason. It feels like it's going to stall and is idling kind of loud.

I have a 2000 Toyota Sienna that has had a check engine light for a while. The light would come at times, and go away at others, with prolonged intervals (days, weeks, months) with or without the light.
Suddenly it started losing power, especially on hills (even a small hill). The codes I read are (I include code interpretations from internet search):
P0300: Random or multiple misfire.
P0301: Cylinder 1 misfire.
P0304: Cylinder 4 misfire.
P1130: Air fuel sensor
P1150: I have not found a problem definition for this code.
Might these codes be indicative of a particular problem, or is each problem more likely a problem with its own cause?

I changed my plugs a few days ago on my 96' Taurus GL 3.0LI checked under my hood to check the recommended gap size and it said .42 to .46.. I went with .46. after putting them in i started the car up just fine, but later in the day i noticed when I came to a stop at a red light my car would sputter and my check engine light would start blinking. When I'd accelerate and drive it again everything would clear up and the light would stop blinking. I didn't change the wires, just the plugs in case you were wondering but I am unsure of how much that would influence my problem. Today after work i had a little trouble starting my car. After a few tries it started and my exhaust smelt rich in gasoline. Did i gap them too much? Should i get new plugs again and regap them? should i buy new wires also?Is my ignition coil going bad?
