Well check engine light came on again and thats what poped up. Checked wire and its good so its plug or coil. Question is ... what plug would ya'll recomend? only mods are CAI and no u bend or cat. Thinking maybe a colder range plug? been browsing on here just checking but any info would help. thanks

how did you test the wire?

I didn't. My wife was driving the car when it came on and took it to a family friend who scaned car. She said he tested wire and that it was ok. So I'm going by his word.

I was only asking because a VOM cant check impedance or arching under load. Perhaps he swapped wires, coil packs, etc.

I'm gonna use her exact quote... lol "he used this pointey thingy and touched it to each wire. he said if wire was bad it would spark" She did say it sounded as if engined speed up as he touched each wire. lol thats what i get for wife driving my car

Oh dude, you and I could swap stories on Wife Automotive Diagnosis. I have had similar type explanations, some just boggle the mind.
