Chevy 1999 tahoe 5.7 vortec ... Car hesitates engine light reads random misfire at auto zone. Took to dealer said 10 degrees out of time on his diagnostic machine. Replaced just about every thing on engine dealer said he couldn't fix because he couldn't adjust distributor, I told him on my car that you couldn't adjust timing from distributor, who is right?

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?
Prius (2001-03) :: Warning Light Came On / Random Engine Misfire - Code P0300
Had this code show up after the warning light came on and then the light went away after two day, the car seems to be a little sluggish now. I have read that this is a random engine misfire and it could be a bad plug..
View 1 RepliesElantra XD (2001-06) :: Random Misfire Code That Would Come And Go
We have been fighting a misfire code for about a year now and I'm pretty sure I finally found the cause. Last Spring the car died on the road and we had it towed to a local service center where they said the fuel pump was bad...this was the 2nd in about 2 years (previous owners doc). We had it replaced and the car was fine but as mentioned had a random misfire code that would come and go. In the last month the car has left us stranded several times and then started after a few hours or a day. While checking the connection to the fuel pump with a meter and test light I verified the pump was getting power correctly to the 5-pin connector but would not start. I unplugged the connector and the 1st 2 pins in the harness connector were damaged and probably burnt.
I cleaned it and applied dialectic grease and plugged it back in turned on the key...fuel pump primed and then the car started and ran fine. It then started to randomly turn on and off but not enough to stall the car. I wiggled the connector and the it I could make it run or shut off. Obviously the connector is bad and the contacts are intermittent. While driving the vibrations would move it just enough to make it cut on and off and more than likely cause a misfire code and sometimes stall the car. My problem now is I can't find a replacement connector/pigtail for the harness connector anywhere including the dealer. Where can I get a new connector for the 5-pin fuel pump harness connector? I have found a MAF replacement connector that looks very similar but not 100% sure if it's the same.
Elantra MD (2010-15) :: Running Rough / Check Engine Light Came On And Misfire Code
In the last month, my car has had an awful time starting on 2 different occasions. The first time it ran really rough for about 1 minute then was ok. The second time was the same but the engine light came on. Took it to an out of town dealer and he said it showed a misfire code but could never find anything else and all looked OK. Spark plugs?
View 4 RepliesElantra XD (2001-06) :: Check Engine Light (cylinder 3 Misfire)
As the title says I have plugged a code reader in and it says "cyclinder three misfire". So I pulled the plugs and good god they were nasty. Some having a gap of 80-90 thousandths of an inch. So I figured the plugs were the source of the problem, thus I replaced them but to my dimise the check engine light is still on, and still reading the same ol' "cyclinder three misfire". I have put 350 miles on it in 24 hours of changing it to allow for proper time of the circuit cycling for the light to change but not sure if it takes longer...?
I also went ahead and checked the plug wires resistance when I had the plugs pulled and they ranged from 1.5-2.5k ohms shortest to longest (cylinder 4-1). And if your curious the magic cylinder three was around 2k ohms for however long that wire is, my guess would be 18 inches. Would this be out of tolerance, I know the norm is 10k ohm for every 12 inches or so...?
My next guess would be replacing the power pack or I guess you car guys call it the "ignition coil"...? I will say that the car does run much smoother after replacing the plugs.
Ford - Taurus :: 1998 - Check Engine Light Is On And Code Reads P0411
98 Taurus, 6cyl, 3.0L OHV, 184K miles. Check engine light is on and code reads "P0411 - secondary air injection system - incorrect flow". This is my son's hand me down car and has a rather large exhaust leak that I plan on fixing. Could this code be related ?? I found out that the CEL has been on for quite sometime now and the car is due for emissions testing (state inspection) in October.

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.

I own an 04 Hyundai Elantra with around 196,000 miles on it, and have run across a problem I haven't had to deal with before. A few days ago, my check engine light came on while driving. I didn't really notice much, but when I started it again it began idling roughly. I got it home and pulled the code, which was P0341 (camshaft position sensor). This isn't the first sensor I've had go on the car (I replaced an oxygen sensor and throttle position sensor a couple years ago), however I ran into two problems:
1. How likely is it that it's the sensor that's bad as opposed to something like the timing belt or VVT adjustment?
2. Since the sensor isn't horribly expensive, I decided to try replacing it, but I can't get any socket to fit on the bolt that secures it. I've heard it's a 10mm, but nothing seems to fit snugly. Maybe there's just so much crud and corrosion that it's ruined the head. I tried using an extraction socket, but no luck.

I just got this very nice Elantra 04 with 64k on it. Yesterday suddenly I got the check engine light on. Today I went to Auto zone and they have checked my car and it showed code P2626. But there are more than a few suggestions about what could be. I don't know what to do. See the attachment below.
View 1 RepliesElantra XD (2001-06) :: Code P0128 Check Engine Light - Faulty Thermostat
I recently had the engine light come up on my Hyundai Elantra 2003. I read the code with my cheap little code reader with the torque lite (free) app on android. It threw the P0128 code which means a faulty thermostat.
Here's the web link to all the details on the code: [URL] ....
I have checked the coolant level and its good. The strength of the coolant is good to -40 Celsius. The engine fan is not running at all. I recently changed the thermostat. I'm leaning towards faulty ECT. The car takes forever to blow hot air too. It has done weird readings in the past with the temperature gauge in the cab.
I just bought a infrared temperature reader of Amazon and want to check the temperature where the water comes out of the engine past the thermostat and compare it to the reading on the torque app readings. I'm thinking it won't match.
Elantra XD (2001-06) :: 2004 GT Check Engine Light With Code P0420 Listed Twice
I bought an 04 elantra a few weeks ago. The check engine light is now on and I get code P0420 listed twice with my code reader. I have replaced the downstream O2 sensor and reset the codes only for them to return again. It is my understanding that this is going to be a convertor problem. My question is that from the research I have done it looks as though this car has two converters. One at the exhaust manifold and then another in the tailpipe. Which one is going to be the most likely causing my Check engine light to come on. Or do I need to replace both converters.

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?
View 1 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 2 RepliesHonda - Cr-v :: 2001 - Check Engine Came On / Cylinder Misfire Code
I have a 2001 Honda CRV with about 140,000 miles. It is an upstate NY car, so has seen its share of salt and rough winter driving, has a little bit of rust.
I recently brought it in for repairs because it was overheating. It was over the holiday weekend and I had a job interview to get to so I brought it a chain, which was the only open mechanic I could find. They told me there was a coolant leak and replaced the radiator.
The next day, the check engine came on. Cylinder misfire code. I took it back to them and they wouldn't give me a straight answer on what was going on but insist they told me that would happen and it needed more repairs which I had apparently refused. They told me it's probably the spark plugs/wires are old but maybe there's more damage, but basically that they didn't want to deal with it.
So I brought the car to my regular guy. He says, yeah it needs a tune-up. So he replaces the spark plugs and wires etc and gives it back. I drove it for a day and the light came back on. So I brought it back to him again and he refused to do anything. Wouldn't give me some possible causes or explanations, just says come pick it up. Didn't say stop driving it, take it to a dealer, he just reset the check engine light and said its probably fine.
The next time I drove the car, while it was warming up the check engine light was flashing. By the time the engine was warm the light had stopped flashing and was on.
Sonata I45 (YF - 2011+) :: Engine Check Light Code, P0711 / Transmission Shift Occasionally
I own a 2013 Hyundai Sonata. Two months ago I realized that my transmission shift occasionally while I am driving, especially when the weather is cold and I park my vehicle for more than one day. Then my engine check light came, after two days it went off. I went to the dealership and ask for a multi-point inspection (without telling the inspector the transmission problem), they recommend a transmission fluid flush, then I went to an auto part shop to ask for reading engine check light code, they see P0711. After researches online, I understand this code is about transmission fluid or transmission fluid sensor defect.
My question is that, would a dirty transmission fluid cause the P0711 code, as some people stated online ?
