Ok here is the problem, I have an 86 GXL and only when its under load itacts like its being starved of fuel I mean it doesn'tbackfire are anything like that it just cuts out and it does this at any rpm. Sometimes i will drive just fine and others it will just stumble just for a second and then its ok again until I put it under load again. I have know clue as to whats goin on I have new plugs,wires,injectors what else could cause this! Please help this is my daily driver until I get my TII Back on the road. Any suggestions would be greatly appreciated!
Sorry for the spelling Im writing this on my lunch break!

 

Had a tune up lately?

Change Air Filter, Fuel Filter.
Possibly dirty injectors.

I'd do the basics first, and if that doesn't fix it, then you can go on.

 

Here is a thought. Have you been getting worse gas milage as well? If so you might want to check your cats (might be cloged). Just a thought

 

well I don't have any Cats and the injectors are new, fuel filter was replaced about 3,000 miles ago! Any other ideas!

 

This is just a Guess but, would a bad ground have anything to do with this! My grounds are good as for as I can tell!

 

There is a little screw at the end of your fuel rail, under a plastic cap, see if that is loose. It can cause fuel pressure to be low.

 

Sorry, just replaced the pulsation damper about a 1000 miles ago, but I will check again! Thanks

 

What about the fuel pressure regulater?

 

Ignition coils?
Are you getting any ecu codes?

 

Check and make sure the vacuum line to the pressure/boost sensor has a orifice in it.

 

saprk plugs/wires

 

I think I figured it out, I have been running a premix in my car because my OMP is disabled. I checked the screen on the fuel pump and it was all gunked up! I cleaned it and now it seems to be running fine! Thanks for the input Guys!
