DmoSc400 Posted March 22, 2009 Share Posted March 22, 2009 Hi I have a 1994 Lexus Sc400 with 120k miles.. I have to give the car gas for it to start.. It won't start with out giving the car gas. Then When it warms up it idle fine. I never had that problem b4. I would start and it would rev up and the normalize to idle. Can someone lead me in the right direction. I have resently change the fuel pump could that be the problem? I've heard from someone it could be ICV. Is there a way to check if its bad with out replacing it yet. Also Looking for a tan driver side door panel. Quote Link to comment Share on other sites More sharing options...
jzz30 Posted March 22, 2009 Share Posted March 22, 2009 alot of things could cause this. cold start injectors, mass air flow meter, or even a simple temperature sensor. you will have to go down the list. if you buy an oem repair manual they have a diagnostic proceedure.
