hi all,this is the problem, i have a 87 N/A ran great and had the normal 3800 rpm stumble but didnt bother me..now it stumbles going up to the 3800 rpm..fuel filter was changed Tps is set, im thinking the grounds are probably bad,could someone shed some light on the subject and let me know where the grounds are??thanx in advance..

 

I found that re-wiring the fuel pump tends to help, took me 13 hours though. You might want to try the re-wire, it might help you out (also if you do the re-wire, pick up some redline fuel injector cleaner...its good stuff!)

check out the fuel pump re-wire walkthrough on

check your plugs.

 

thnaks guys, let me try these things and see what happens..
