Hey guys, Im not an advance cat in engine work but need some help. I got a 95 z-28, gut cat, freshly built trany and engine(just new bearing seals, nothing expensive.....) but done to the story, I have no problem once the car warms up but when first starting over it seems as if the car is getting to much air. by that i mean its ideling at 400-600 rpms(not stable just going up and down) and if i reverse bring it to say 1000 rpm and let go the gas it kills out b/c rpm drop rappedly down to 300 and will die out. keep it mind its always from a cold start.
from what i have be told.. to believe is the o2 sensor and i need a "dead" sensor? something that says to the computer its working fine b/c the cat is no longer there... but i dono im lost more than ever and tired of reversing and dieing ,starting ,reversing ,dieing.... i need help or im going to shoot my foot soon so i dont have to drive .... alrighty well if you can or have some personal advice or need more info email (lionelb@hawaii.edu) or post please... ight peace
