Default PLEASE HELP!!!!!!!!!!!!!!!!CAR MISSING AFTER HEADER INSTALL?

Installed headers about 5 weeks ago on my 01 Z-28. Have about 600 miles sence the install. Just this week, the car started missing at WOT. please help, i don't know what to do. I hate to drive the car in this condition, but i can't afford to take it to the dealer. The SES light went on for about 10 seconds so I had auto zone scan the PCM, but no stored codes were found?????????????

any ideas.

Most common problem after header install is loose wires, have you checked them?

yeah, I checked for the wires comming off and to see if the headers were melting the wires....everything seems okay. I changed the fuel filter as well.

did you overtighten a spark plug and crack one of them???? I did that once (dumbass!!) when I was about 17.....and about 2 years ago a buddy of mine had a Factory Dud Plug...looked good...no spark at all....

Check the plug wires and recheck to make sure no wires are getting burned. Could also be a bad plug as I've seen that a few times.

Make sure you check for loose plug wires or it could be a bad plug.

If the SES light cam on, there should be a code. I don't know how much I trust Autozone to diagnose a problem. I'd get Autotap and check it myself.

TR55s and leave the gap alone.

I had the same basic thing happen, and I just changed the plugs and it fixed it. One of the plugs must've hit the ground the wrong way or something which opened up the gap on it. You also might just have a dud plug like it was said before.

Good Luck.

Get tr55's and invest in an autotap-it'll do the trick.
