misfires!!!!!!
 
They don't go away. 5,6, and 8. New plugs, wires, coils are good. where do i go from here? This has been a recurring pain in the @ss and I can't seem to find a solution. :confused:
2002 DII SE 90k miles.

How new are the new plugs? What brand and size? If they aren't magnacore 8mm, it could be your problem.



Also could be like me and have a stuck open valve, but I doubt it

What plugs and wires did you use?
How long ago was the tune up done?

I had the same problem last month. I replaced my two front 02 sensors and problem is fixed.

what plugs and wires?

Bosch platinum +4's and spark transfer international wires. Tune up was done about 1600 miles ago.

i never even heard of those wires... what did they cost what size are they? i suggest you spend $80 and get the magnecor 8mm wires.

spark who???

Arizona man 10-20-2009 12:35 PM

The shop that replaced my head gaskets, which also seem to be going bad installed those wires at the same time 1600 miles ago. I guess you have to do everything yourself if you want it done right. The shop charged me $74.99 for them. Don't know what size they are.
