Won't Idle At Start....

[DmoSc400]

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.

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.
