ok heres what happen. i was running an open header for bout 2 iweeks becuz i was n the process of removing my cat to fix it. well i just gutted the cat and put it back on my car. so now when im driving it just decides to kill its self, if i just try to restart it idles really ruff, but if i take the key out and put it back in, and start it, its all good. so i dont know what the prolly is, and ne suggeston would be great thanks

 

try adjusting your idle...
mabey there is a crack in your intake tubing causing you to lean out....

 

well i know that my idle screw is really really low becuz it was idleing way to high so i tried it down alot. and i noticed today that it happens when im giving it a lot of gas

 

Does it shut off only when your giving it gas, does it do it at all when you press down the clutch?

 

na its only done it when im giving it alot of gas pretty much floored, like around a corner or going straight, then it just does shuts off and i have to reset it, but hasnt done when i had the clutch in at all
