If the misfire remains on the #2 cylinder after swapping the cop then it could be fuel related, possibly a sticky/leaky injector.
since you have an 02 sensor coming for it I would say that should take care of your first issue. If it doesn't then you need to look at the wiring to that sensor.
ok i got the o2 sensor in and put it in last night... that fixed the rough starting idle... LTFT 0% both banks and STFT go from -3% to +3% on both banks... perfect readings now...
on another note i dont have much funding right now, so i went with the cheep chinese COP's. i bought 2 COP's for 14$... i couldnt resist... i got another code thrown today checked it, and it was only cylinder#2.. so i changed the COP with the chinese one.. bingo!!! no more miss.. i went to the store just to take a drive and WOT purrrrrfect... i just hope the chinese COP's last for a while.. the COP that was on cyl#2 was original with the date code of 2002... so for now my baby is fixed... just FYI the chinese ones really look very well made but we will see...
my next torment is my idle fluctuates, i already have a new IAC but havent put it on yet... when i put it on before when it was running badly it stalled my motor like crazy... so my next question is should i replace the IAC with the new one and also reset the KAM with the battery... or what do you think?
thanks for all the advise and please let me know...
