I have a misfire on the number 2 cylinder on my 97 Nissan Maxima 5spd. The computer has been changed 3 times, and it'll work for a short time after the new computer is installed, but then the problem resumes. What would cause this to happen? The coil has also been changed.
View 7 RepliesI have a 2002 Nissan Maxima GLE. I had had problems with it misfiring. It said it was misfiring on cylinder 6. Put all new spark plugs on it, same problem. Put new ignition coils, still same problem. Had it checked by several mechanics. NONE of them could find why it wasn't getting power. Then about 2 weeks ago I was driving it home & it died. Got it started & it drove less than a mile & died again. when it died that time, I suddenly had NO POWER to anything in the car. Lights don't work, no horn, no radio, no beeping when key is inserted--NOTHING. if I let it sit for a day or two, it will start clicking & then interior lights will come on--until I put the key in it & turn it over. Then I am back to no power. It does not crank or anything when I turn the key over. I have had the battery checked and they said it is still good, had 100% charge--even after being off the car for over 24 hours. I have been wondering if it is the ignition switch or starter...
View 19 RepliesI haven't had a check-engine light yet, but at idle, my 1996 Maxima has a sporadic misfire -- there's no rhythm to it at all. Does this sound like a symptom of a coil going bad? What would be a good way to test them without having to replace all 6 of them? The car has about 175,000 miles on it. I just put in a new set of NGK iridium plugs, and hope I didn't damage any wiring in the process (that doesn't seem likely, but I guess I can't eliminate that possibility).
View 16 RepliesI have a 1998 Maxima with 57K miles on it. I just bought it about a month ago. Anyway, a week ago I noticed It felt very "choppy" when I shifted into Drive or Reverse. It felt like it was going to stall but it never did. The Service Engine Soon light has been on for about 3 weeks but now, when I go up hills especially, that light blinks. I can still drive it but I shift into Neutral at stoplights to avoid hearing the rough idle while in Drive. Went to Pep Boys yesterday - they had the car for about an hour and then informed me that they would need to keep the car for a full day because of the "complex issues involved" - especially concerning the codes. The codes they read were:
p0300 random misfire
p0325 knock sensor
p0440 evap emission
My car passed smog test abut 3 months ago. I can drive it OK it just is very choppy and so there's not a lot of power, especially going up hills.
1994 Maxima SE 5 speed manual with 178k runs great when engine is cold, then a cylinder starts missing. Symptom is worse in low gears. Then, miles and miles without a miss. Replaced rear ignition coil and it seemed to fix the problem... for about 20 miles, then it started missing again. And stops missing… for miles.
View 2 RepliesI have a 1997 Nissan Maxima. The past few weeks, it sounds like it's getting harder and harder to start. Last week, it wouldn't turn over, and had somebody jump me. I took it to Pep Boys and they tested the battery and alt and said both were fine. Tonight, it wouldn't start again, I had somebody try to jump me and no sounds/no activity. About an hour later, I went back to get my car and it was able to start..
View 6 RepliesI have Nissan Maxima 1997, yesterday I was not able to start my car and so my mechanic replaced Starter. After replacing starter car is starting but now when I start driving it just starts for few feet's and stops suddenly. When it stops engine also stops, I can start car again and it again drives and than stop completely. This is happening continuously when I do reverse or fwd driving both. I suspect that this has something to do with replacement of Starter, during replacement my mechanic dismantle few things to reach the starter and I doubt that some part is not loose and not plugged in properly. I never faced this issue in the past.
View 12 RepliesI bought a 1997Nissan Maxima from my cousin and as he tried teaching me how to drive stick I stalled and the car did not want to start back up we were able to pop start it it to get back to my house. I am unsure whether it is the ignition switch or the relay because the car will start sometimes after I keep trying to start the engine for a while...
View 18 RepliesSo my Nissan emits a loud (way louder than normal) "vroom" when I start it up and then idles back. Also, sometimes the tach needle jumps high and then falls, sometimes almost seems like the car might turn off. I have a knock sensor code on and nothing else. I was due for state inspection and the guy told me that my exhaust was warped and said that it was too loud and I will fail the inspection (I think he meant on the noise level as he did not do any diagnostics.
View 1 Replies1989 Nissan pathfinder. 6cylinder - VG30i - Manual trans - Throttle body injected. No CEL.
I've been trying to diagnose a misfire on my 89 Pathfinder during my lunch breaks. I just changed out the the plugs, dist. cap, dist. rotor and wires. Still misfiring.
When it starts-up the misfire "putt" is random, but once the idle lowers to about 1k it gets very rhythmic and just sounds like part of the idle and the car vibrates a little too much. Stinky exhaust (obviously) but no blue smoke or anything.
Finally bringing the car home to do some diagnosis over the weekend. Next I'm going to do some cylinder compression checks and vacuum checks. Probably check fuel pressure too. Is it odd that I'm not getting a cylinder misfire CEL code? The manual lists the code type.
It keeps reading the code P0303 "cylinder 3 misfire". All coil packs, fuel injectors, spark plugs have been replaced. The exhuast smells normal. The oil is the correct color(maple syrup color, NOT milky). It's not blowing through coolant. Compression test came back normal. It's not the cat converter because the exhaust doesn't smell like rotten eggs. The car is sometimes hard to start. it hesitates/stumbles and shakes really bad. It feels like its not getting enough power.

I have a 2005 Nissan Sentra with 75,000 miles on it. Several months ago (see above link) the check engine light came on with a P0304 cylinder 4 misfire code. The only symptom appears to be a rough idle/shaking every 3rd or 4th start for the first 10-15 seconds, but runs smoothly afterwards. My mechanic replaced all my spark plugs (I had new plugs put it at 50,000 miles for the same issue) of which the one from cylinder 4 was worn down much more than the rest. The problem persisted so they replaced my fuel pump and fuel filter and switched the spark coils from cylinder 4 to a different cylinder, but the code still read cylinder 4 so it wasn't the coil. That was back in October.
I took my car back in last week for the same problem and without starting my car (because the problem is worst on the first start) they pushed my car into the bay and did a smoke test, no leaks in the fuel lines. Then they checked the cylinder and said that there was "excess" fuel in the cylinder and replaced the fuel injector. Then after ~3 days the check engine came back on with the same P0304 misfire code. Previous repairs/diagnostics rule out spark plugs, coils, fuel pressure, and injectors.
have a 1997 nissan pickup 2.4 liter engine check engine light came on code say number 2 cylinder misfiring put in shop. they say that they can't get to misfire.truck run great.just that light keep coming on with code (p o 302)

View 8 RepliesMy dad's 97 dodge neon is showing a misfire in the number 4 cylinder. He replaced the spark plug but still getting that code and engine not running smooth. What other things could cause this? Engine has about 130,000 miles on it, had been running fine.
View 9 RepliesMy truck has developed a misfire on cylinders 1 and 5. The OBD2 scanner at autozone says code P0300, Po301 and P0305. I bought a new set of plugs and wires. Problem still there. I then replaced the both coils. Problem is still there. Is there a control module or something that could kill those 2 cylinders like on the older trucks with distributors?

View 1 RepliesI have an 01 5.4 Triton with engine light on I put it on the scanner and it read miss fire on cylinder 6 and 1 I changed the cops and plugs boots and spring erased the codes but the check light is back on and scanner is say miss fire on same two cylinders u can hear it in the exhaust u can smell gas when sitting at an idle around 40 MPH has a slight engine shake goes away when u accelerate I am not sure what else to do some one told me to check for vac leaks and fuel pressure.

View 5 Replies1997 chevy k1500 ... I have a misfire on cylinder 3 that i cannot figure out the cause. The idle is rough, backing out after starting is very rough, it seems to pick up at higher rpms but once the truck upshifrts to the next gear it shakes like a leaf in fall. within the past year the engine was rebuilt all new seals a new fuel pump, new injectors, new everything practically. so far i have done the following:
compression test results:125-130psi
fuel pressure test results: 50psi once primed, 50psi with engine running, no immediate pressure loss after engine is shut off
new spark plug wires
new spark plugs
replaced all four o2 sensors
So my 99 F-150, 4.2L started throwing a code a few weeks ago, P0306 #6 Cyl Misfire. This thing has got 238,000 and has been the most reliable commute vehicle I've owned.
Today I changed all the plugs and wires (they were due anyways) which didn't resolve the issue. After clearing the code, got about 3 miles out and it came back. Running SeaFoam through the system on this tank as well, but I'm leaning towards an EGR blockage like what is described here:
Sparky's Answers: 1999 Ford F150, P0306 Misfire Cylinder #6
I was about to buy a new coil pack but I'd rather not continue to throw parts at this, as I've read many others do with this same exact situation, only to end up with the same code. I've replaced the coil pack once already a few years ago when I lost a cylinder on the way to work.
