Crazy pulsewidth

[abiba_69]

So, my car seemed to be running a little funky. By this i mean when i would start the car, it would chug and fart and almost stall. I have to keep some throttle on for about 7-10 seconds then it evens out. So for the hell of it, i tossed a noid light on one of the injectors. When i would hand operate the throttle, the noid light would go MENTAL! Like retarded amount of injector pulsing. What would casue this?

Thanks,
Chris

Injector pulse width will increse with TPS movement, lower Map vacuum, lower coolant temp, lower air intake temp or you may have a problem with the control side of the injectors.
Any fault codes set?
