Blinking SES light after plug change
A little more background. My SES light would come on when holding the rpm's at 3000-3500 and stay on. It was the pe300, and it would stay on, random engine misfire code. I would erase it, and then it would not come on again until I did the same thing with the rpm's.
Changed my 2year old TR6's with new TR6's tonight. Bothed were gapped at .030".
Now when I hold the rpm's the SES light will blink, then go away after a while. Havent had the chance to scan it yet, but my guess is the pe300 again.
Havent sprayed it in over 1 yr. Also the car still runs strong no misses or anything.
Maybe the knock sensor?
Any ideas are appreciated. Note: changing the plugs for the first time is a GOOD time.
thanks,
justin

Ya, but dont I need to keep the gap down for nitrous?
I have a wideband and it appears to be running lean WOT now. about 13.7. At WOT I dont get a SES light though, only when holding the rpms around 3/4k.

How big of a shot do you have? Maybe try .045. That should be fine for the spray too.
I mean barring a cracked spark plug or broken plug wire......or maybe having a spark plug wire that is touching an exhaust manifold pipe..........that small .030 gap is all I can think of.

A long shot, but you could try a CKP variation learn. Since you had misfires codes before the plug swap.
