i have a 92 rs 305 tbi the car i think runs decient but today i pulled out my plugs and they were all carobon fouled and im sure thats causing me to loose some power does ne one have any idea why they carbon i think its from to much fuel so i checked the fuel pressure and it was at 10psi could it be a bad injector leaking gasket fuel pressure regulator bad tbi all together i really need some ones opinion

 

how many miles are on the car??? maybe the plugs have been in thier for quite a while. Maybe you should check the fuel regulator?? Good luck.
