[s-cars] aw, come on, continued

Thu Mar 6 04:14:41 EST 2003

I haven't followed the thread very closely (foot poised very close to my
mouth) but have you swapped your plugs & plug ends for a known good set?
I've had mine do something similar to yours - under heavy loads (sudden
acceleration and going up hills) it would miss/stumble, but once it got
going (WOT) it was fine. I tested the plug ends and found 3 of them out of
spec so I changed the plugs as well at the same time.
