mine was miss firing on 3, new coil pack fixed the issue.

 

That will be the first thing i check tomorrow! Im pretty sure i got it really tight, but you never know...thanks

Yeah, if thats the problem i might as well do all 8..

 

Don't just make the spark plugs really tight. You need to actually torque them to 14-16 ft/lbs. The heads only have 4 threads on them and improperly torqued (too little or too much) will blow them out.

Don't waste money replacing all the COP's. Take the #6 COP and swap it to another cylinder. If the misfire follows it, you know it's a bad COP. Just replace the bad one. No point in replacing 7 good COP's.

 

got home late from work so i couldnt check it...... didt have a torque wrench so i have no clue how tight i did them haha...

well the car has 108k on her so i wasnt sure if it was time for a COP change but if its not worth it ill just replace the one that is bad...
