I finally changed out the last plug (wow!) and it runs smooth with no stutters, burps, farts etc. The plugs that were in it were there for about 18k and looked well used but none were oily, broken or overly fouled. About 2-3 days after changing the last plug I got an SES light. I disconnected the battery to reset and in about 2-3 more days it comes back. If I need to go to the car doctor I will but is it possible it could be something typical that I may have caused or overlooked when I changed plugs? Understand I changed the first 7 on one weekend, then about 2 weeks later I changed the last one. After the last one is when the light started. I don't see any loose hoses or connections and I have checked and rechecked. I don't see how I could have crossed anything.

It's had the same mods for over a year:
2-prog Superchip, 4# pulley, B-bypass, K&N panel.

Plugs removed were TR5-new ones are TR6-gapped at .038

Any ideas or should I just turn it over to a dealer? There are no tuners I know of close by to take it to.

Thanks for ANY help.

 

take it to an autozone or some autoparts store that will read the codes for free. that way you know what the prob is

 

if all you did was change plugs then check to be sure all vacuum lines are reconnected

This time I used a mirror and a flashlight to make sure I could see everything, and yep-there it was-a vacuum connection not made up hidden out of sight by a wiring connector. I am stupid but at least I'm happy. Thanks for tolerating

 

Good Deal!

I give you 5 for suggesting I do something I thought I already did well enough. Just goes to show - you just can't see everything all the time and you may need to take a different view.
