Okay guys, here's the problem: I recently changed three fuel injectors and also got a new starter. Everything seems to be normal when i start up the car. After a few seconds, my RPM starts to drop from 1 1/2 to 0 and then the engine turns off. I don't know what the problem could be. The only way that i can keep the car on after starting it is if I step on the gas for about a minute or so. Performance is fine but the starting up the car issue is a biotch. Can someone please rid me of this annoying problem? Thanks
