Cylinder 1&5 misfire and random misfire.

I just installed my udp and right when i punched it the check engine light started blinking for 10 seconds or so then went off. I got on it again a few minutes down the road and it did it again. then I did it one more time and now it's staying on. Cylinder 1&5 misfire as well as random misfire. Would it have to do with the udp or do you guys think it just so happened to go on right after??

Did you reset the ECU? Check the spark plugs and coils.

I did. It seems that it fixed its self. I only had this problem when punching it in first gear. I have done it a few times now without it happening.

That's really strange. UDP should have nothing to do with a misfire. It just started/stopped out of nowhere?

Yep and only in 1st gear. I haven't had this problem the last 10 punches. So I think it sorted its self out. I was thinking maybe it had something to do with the alternator moving slower.. idk??

No idea how. But haven't had the problem in a bit. Once I took the neg cable off it did it for two runs but then it hasn't done it since. Never felt any power loss or any backfires. It sounds and felt perfectly fine.

Thats strange, never had that problem either with the udp.. But since you floored it in first gear has the CEL come back on after it went away?

It did 4 times. I disconnected the battery and it continued for 2 more times and then it hasn't occurred again the 10 other times I have done it. So I think the computer fixed it. I think it had something to do with the alternator because i used the cars starter to break the crank bolt.

When I had that problem it was for bad spark plugs. When a past friend of mine had that problem it was also because spark plugs. It will only occur usually when there is excessive wheel spin & you just cant grip. I'm guessing because at least one cylinder cant keep up (spark plug, coil etc) or because so much constant wheel spin that car just starts panicking & flashes cel

The cel codes would be at least 2 cylinders p0305, p0302 & thirdly p0300 (all cylinders misfiring)

It's a pretty common practice. Done it on many cars. Though I have never had any problem with it. I was think maybe if the engine did a few turns while cranking it (but not all the way to on) maybe the computer saw the alt wasn't being used and threw that code.

Huh, well, I guess I'm with Sonnick on this, I wouldn't do it.

Anyway, I put the UDP on as well recently, and had no issues. Feels a little quicker in 1 and 2, but I'm going by the butt dyno, and we all know how that works.

I since my car has 60k and as far as i know it has never had the plugs changed i decided to do it myself. I go to take out the first plug and it spins right off, and i mean with ease as in i could have done it with my fingers.. So, I'm thinking that may have been my problem. I would think I'd have less pressure and thus less power but I never noticed anything. I'll take the rest out and see whats up. Oh and the spark plug tip was very white..

Glad you checked 'em! That definitely could've been your issue. White means you are running a bit lean. Time for some exhaust mods

If I knew I could get a straight through exhaust that was very quiet I would. I'm outside while typing this and these rear plugs are a hassle

I had a 22 long 6in across resonator and a big muffler on my last car and it was still loud as hell. I also don't want to spend 300+ on two mufflers. Then another $100 for res and another 150+ for pipping for 7-8whp.

I doubt you've put one on if you think that. I do have one and tried it first but like all others cars it simply fails. The first wrench I used didn't work. It was on there so tight it actually broke it so I had to get the 1/2 out.

You have to use an impact like this one. It spins that bolt off and laughs at it. Hahaha

I got a 2.5" catback mandrel bent with basically new mufflers for 400 shipped

I had a 3/4" drive impact running on 180psi and it would not break it. I got a 4 foot pipe on my 30" 1/2" drive breaker bar, and leaned on it to the point of twisting/bending the whole wrench and extensions almost 90 degrees before it popped. That sucker was ON there!

Not exactly sure how the alternator can help things here, guess I'm curious now......
