Accent MC (2006-11) :: 2010 GL - Misfire On Cylinder 2 / Code P0302
I have a 2010 accent GL manual sedan. It has 104,962 KM on it, the warranty expired December 18, 2015. Since February this car has become a frustrating money pit. Being in the dealership constantly for repairs, then within a week something else 'happens' and back it goes. Spent almost $5000 in 4 months on repairs. Decided that's enough and will do majority of repairs myself.
Yesterday while drive on the highway I had a sudden loss of power and a check engine light came on. My scanner which has become a standard item in my glove box indicated a misfire on cylinder 2 - P0302. I limped the car home, in 3rd gear I was having a hard time staying above 2000rpm at 60km/h. at lights I had to use hand brake so I could keep my foot on accelerator, revs were dropping below 300.
Today I replaced all the plugs (all 4 were still in good or better condition, #2 showed signs of a slightly rich burn and #3 a slightly lean burn), replaced all coil boots (no cracks, no burns, and still pliable), removed and cleaned all the injectors. Error code P0302 persists.
Passat (B5) :: Misfire Detected - Error Code P0322 And P0302
I bought my first VW about 3 months ago (so excited!) It's a 2003 Passat, 5 spd, 1.8t. I've had one thing happen so far (until yesterday). On 4 separate occasions when I'd go to start it, it would crank for a few seconds before it would start. Then once it was running the EPC light would turn on. It seemed to be running normally but I turned it off and restarted it and it started normally and the light extinguished (the first three times). The last time (about a week and a half ago) it kept doing it each time I started it, and upon starting probably the 4th time in a row the MIL came on. I drove it about a mile, turned it off for a few minutes, then turned it back on and it started normally with no malfunction lights on. It's been normal since then. Until yesterday...
Yesterday as I'm accelerating from a stop light (I think I was in 3rd) all of the sudden the engine started running really rough and the MIL came on. I turned around and drove about 2 miles back to where I started at about 20mph. The MIL would be steady while coasting and flash while pressing the accelerator. I got a hold of a diagnostic computer and it came up with 3 codes...
1) P0322 Ignition/Dist Engine Speed Input Circuit No Signal
2) P0302 Cylinder 2 Misfire Detected
3) P0302 Cylinder 2 Misfire Detected PENDING
Passat (B6) :: Error Code P0302 / Misfire In Cylinder 2 - Oil On Spark Plug
Getting error code p0302, misfire in 2, pulled the plug and had oil on the treads and on the lower part. My guess is the valve cover gasket, but I'm not 100 percent sure.

I have a 2010 model Hyundai Accent showing error codes P0301, P0302. It has a 1.6L engine. I know little about cars, what is going on and how to fix it.
View 7 RepliesAccent MC (2006-11) :: Engine Was Idling / Little Rough And P0302 Code Thrown
So I bought my accent used a couple months ago. It is a 2007 SE 3dr 5spd manual. It ran nice during my test drive and the price was right so I bought it.
Now I'm wondering if there is any way to find out the service history on the car...at least the major one's (30k, 60k)?
I ask because recently the engine was idling a little rough and it threw a P0302 code so I changed the spark plugs and holy-cruddy-deposits-batman those things were black. Gapped the new ones and popped them in and its a noticeable difference. My CEL keeps coming on and throwing a P0496 code as well, virtually once every tank of gas. Its not the gas cap so my next step there is to check the PCSV and hoses.
With these little problems, it makes me wonder about any larger issues. I know the timing belt on these things is supposed to be replaced at 60k. Additionally I would be willing to bet that my ECM software is out of date. Would Hyundai have records for any of the big maintenance milestones since they are required for warranty work?
How much does it cost to have a dealer check your ECM software and update it if needed?
Accent MC (2006-11) :: Several Error Codes - Cylinder 3 Misfire
My 2011 Accent's engine light came on recently. The mechanic said it was a cylinder 3 misfire and recommend changing the spark plug and coil pack for that cylinder. We did that over the weekend. Now the light is back on and has read 5 codes in the past 12 hours (4 at one time). They are P0303, P0304, P0003, P0403, and P0100. I have looked the codes up and can't discern if any could be caused by one main issue. About a month ago it read a code for the oxy sensor, but it went away and never came back.

I have a 2005 Jetta 2.0 BEV GLS. I got a code P0302 for misfire on cylinder 2. I am pretty sure it's the Ignition coil. I live in Canada and my autoparts store only has BWD brand. I have read this is a crappy brand.

I just purchased a 2005 Santa Fe, 4WD, 2.7l..the engine has a miss...the code that came up was "misfire in #2 cylinder"..I checked the coil pack...and the wire harness just crumbled..so I replaced the coil pack...reset the code..and it was good for a couple of days...I got through inspection...today I put on the A/C..and the engine got rough..the check engine light came back on..same code..misfire in #2..I'm thinking the injector or what else could it be? plug? wire?
View 3 RepliesWindstar :: 1997 GL 3.8L - Intermittent Misfire On 2 / Code Reads P0302
I have a new (to me) '97 Windstar with 128K +. C.E.L. is on and intermittently flashing. The code reads P0302 (Cylinder 2 Mis-fire). No other codes are set. Have cleared them many times and gone through multiple drive cycles.
Description of issue: After clearing the codes, and indeed upon each startup, the car starts and idles smoothly without hesitation or issue. It pulls away from parked position without issue. Appears to accelerate just fine. In stop-and-go traffic or directly onto the highway it seems to run smoothly without problem. After a period of time (I don't believe it to be consistent), it will start to misfire and the C.E.L. will be set. If it is still misfiring, the light will flash.
Here's the weird part...when stopping at a traffic light or just continuing to drive on the highway, the misfire will resolve and the car will run smoothly again. The C.E.L., trailing the condition by a bit, will go to solid from flashing and will remain that way until a little farther down the road. The misfire never seems to be more than one cylinder and the trouble code seems to bear that out. Just idling, the car will return to smooth operation and it seems to have smooth acceleration. In other words, the misfire seems to go away under acceleration.
What I've done: I've replaced plugs and wires. No change. Replaced Coil pack. No change.
Next steps: Next steps seem to be looking to fuel or air. My concern with that approach is the occasional nature of the problem. Compression problems would be consistent across the board, right? That cylinder would always be a problem. Same thing for fuel (fuel pump and/or filter). All cylinders would have the problem and it would have issues starting. OK, next thing--injector. Would an injector have spotty performance like this? Also, could it be related to the EGR ports on the intake on this vintage Windstar? (Once again, is an intermittent problem consistent?) Finally, since the primary circuit for spark is controlled by a PCM pin setting a ground for each cylinder, could the PCM, or wiring, be the culprit?
Ford - Freestar :: 2004 - Misfire / Computer Code Is P0302
My 2004 Ford Freestar SEL (the 4.2L version, 123,000 miles) is missing. The computer code is P0302 which, from what I can find, indicates a misfire in cylinder 2. I had this same code at 99,000 miles and ended up having the spark plugs and wires replaced around 100K miles. It was all running fine until about a month ago and started misfiring again, badly. I thought it was related to the rain but it is doing it all the time now. At times it gets so bad, I have no power and the computer disengages my A/C (bad at this time of the year). I tried a running a fuel system cleaner that specifically mentioned cleaning the injectors, hoping the problem was simply a clogged injector, to no avail (I know I probably wasted my $10 here). I have a couple of questions:
1. Am I doing damage to the engine or transmission by continuing to drive it? I really don't have a choice but need to know how urgent it is.
2. Does this thing have a traditional distributor cap & rotor or is there an electronic ignition module the plug wires connect to?
3. Where would I find the illusive distributor or ignition module, in theory?
4. Any other theories as to the cause of the misfire (cheapest first)?
Santa FE SM (2001-06) :: 2002 - Code P0302 / Misfire On Cylinder 2
I have a 2002 Santa Fe 4 cyl that is giving me a problem that I could use some advice on tracking down & fixing . First & most important is a code P0302 # 2 Cyl misfire. How to check the ignition coil pack , injector ,& wire for this cylinder in home garage with normal tools & meter . Is there a you tube displaying how to do this step by step ?
The other problem which I don't have the code for at this time is that some part of the exhaust is not getting warm enough & this also put's the check engine light on . Will get back on this one when I solve the main problem Misfire.
Santa FE SM (2001-06) :: Engine Light Come On With Code P0302 Cylinder 2 Misfire
I have a 2005 Santa Fe with the 3.5 with 112000 miles on it. I had the engine light come on with the code P0302 cyl #2 misfire, I got spark plugs, plug wires to do a tune up on it. I changed all of it and got it back together, started it up and it still had a miss to it. I then took the front spark plugs out and did a compression test on it. #2 was at 85, #4 was at 120, and #6 was at 160. I couldn't check the back cyls because I had already put the intake back on. I then did a wet test, and all the cyls came up to 160. So this tell me that the piston rings are bad in #2 and going bad in #4. I have kept all the oil changes up and up to this point I haven't had any trouble with it. Having this problem with there 3.5?

Santa FE SM (2001-06) :: Engine Having Hiccups When Accelerating - Code P0302 / Misfire On Cylinder 2
2005 3.5L FWD. 5 days ago I left the house, the engine was running smooth at idle but having hiccups when accelerating. Check engine light went on when accelerating but going off at idle. Turned around at the first stop light, parked the car home and pulled code P0302 misfire on #2 . Figured it's most likely the coil, was going to order one next day but to my surprise, no more check engine light next day and engine has been running smooth since then. Probably drove 100 miles since with no issues. I have 6 spark plugs waiting to be replaced but it's too cold to do it right now unless it's an emergency. Car has 105k miles now, spark plugs were changed at 63k. Was this just a fluke and P0302 will probably not come back or should I not risk it and just go ahead and replace the coil? If I end up replacing the coil, should I do one coil or all three?
View 22 RepliesFord Ranger / B-Series :: 1995 - Misfire In Cylinder 2 / CEL Flashing And Code P0302
I have a 1995 ford ranger 2.3 L dual coil packs new plugs, wires, coil packs, tps, idle air sensor, internal temp sensor, and a replaced mass air flow sensor from wrecker. That all said my one son missed a plug when i replaced it , it had no tip left on it , but since then i now have a misfire in cylinder 2 where the olther plug was found and replaced ...
Gap for plugs are .44
Used the wrecker maf to see if it would clear a p0113 which it did. I am stumped on why at approx. 30 minutes of driving that the cel will flash then set a p0302, no other codes no fuel smell. rechecked plugs all are clean haven't been able to check fuel pressure yet, and i out a can of seafoam in the tank to see if it clear out injectors.
Besides all, I will check injector to see if I hear anything but I'm stumped. Also we have to have an emission test so is it best to fail the test and will it show me what I'm missing.
Mazda - Mazda6 :: 2006 - P0302 Random Misfire - CEL Comes On
Mazda6. I have a check engine light for a random misfire on cylinder 2. I have changed the spark plugs, the injector, and even the cylinder 2 coil, but still have that random misfire. The funny thing is that it would run great within short (about 30 miles) one way trips. Lately, I have gotten a new symptom: It has started to hesitate and can feel a loss of power but only once the car has been driven for about ten minutes non stop. Can't figure this out.
View 12 RepliesAccent MC (2006-11) :: 2009 - Low Purge Flow Error Code Popping Up
Not too terribly long ago I got assistance on identifying and fixing an engine misfire on my 2009 Accent. I assumed was directly connected has cropped up again - a P0497 Low Purge Flow error has come up on the car.
We recently replaced the purge flow valve, and everything seems to be running fine - there is no visible cause for the error, and I've even tried making sure I get the fuel cap as tight as possible.
The code is not popping up constantly - this is only the second time it's come up since the misfire was fixed(without obvious symptoms I always clear a code once just to make sure it wasn't a computer glitch), and the first time it popped up on it's own was the day after I fixed the misfire. Need to know what to check to find out what's wrong and, of course, how much priority I should place on fixing this issue.
Lexus GS 2006-11 :: Check Engine P0302 - Misfire On Cylinder 2
Check engine code (P0302). I have a 2007 GS 350 with 116k miles that was driving perfect until this week. My check engine light was initially blinking but is now on solid along with the check VSC light. My question is: of the 6 cylinders (3 on the left and 3 on the right when facing the engine) which one is cylinder 2?
View 7 RepliesPrius (2004-09) :: 2006 - Got Codes P0301 And P0302 / Misfire At Low RPM?
This has been an ongoing issue with our 2006. We purchased the car about a year ago and have put on just over 8,000 miles. Rebuilt the battery pack and replaced the 12v battery. This is my wife's car and I have a 2005, so I have done some diagnostics, tuneup, and even swapped some parts between the two cars trying to narrow down the issues.
Only recently have codes been recorded. The car is has a noticeable misfire at low RPM. Here is what has happened up until now:
11/29/15 - replaced spark plugs - #1 was fouled so I swapped coils between cylinders 1 and 4
2/25/16 - replaced 12v battery with new battery
4/1/16 - P0300, P0301 codes were first recorded and reset to see if they came back
4/10/16 - swapped Integration Relay with my 2005 (part # 82641-47010). My 2005 ran poorly after the swap, so I put a used one in my 2005.
