So... I started my car this morning for school and went down my street but as i turned i looked at my interceptor and it said 32 misfires I didnt feel any kind of bog or stutter or whatever, it was normal. and now it consitanly says 2 misfires right after i shift into 2nd on normal driving. I dont feel a performance difference when it does that either.

What could cause this? or is the guage not reading right?

 

New plugs?

 

yeah it did this a while ago and i got new plugs autolite xp Iridiums and still continued. My old plugs looked fine too.

 

maybe a guage ghost..

 

what about air filter or cat?

 

I haven't had many performance mods done to my car, and sometimes it shows 1 or 2 misfires randomly on different cylinders when im shifting gears. I always figured it was a misread and the misfires aren't that frequent.

 

An extremely random misfire is probably nothing. Maybe fuel filter.

 

mine does it too, if i go to the the misfires menu they are mostly on cylinders 5-8. which the instructions say to ignore if you have a 4 cylinder

 

Mine does it on 1-4 as well.

 

yea mine shows a few occasionally on 1-4, but the 10 to 30 it shows is usally on 5-8

 

well how many misfire at a time is bad?
like 10 or 20?

 

well, even at 4,000rpms, 20 misfires is only about a quarter of a second.

 

i just installed the interceptor
the params are not really telling me anything
if its bad or not >_< it has a number
thats about what i see

 

driver error. jk lol yeah mine does this to sometimes

 

ok i just notice the misfire is when i downshift
or when i punch it.

 

shorten the gap? do you have meth?

 

no meth just 60s 2.7 autolites
hmm i made a new post =p https://www.cobaltss.net/forums/show...76#post3923476
