sometimes it wont start i have to let it sit for like 25 mins. eny one know wut it might
be? also ill mention i have that stupid 3800 hesitation and yes i check all my clean
and inspectet all my grounds and my replaced the variable resistor pack...
oh and all the injector wires are fine too....
eny have some eny suggestions on it????
oh and its a s4 n/a
-thanx

Well, that ws vry hrda to undrstond!
Get your injectors cleaned and balanced.
Are you noticing a drop in MPG? Anything recently done to the car? Have you replaced your fuel filter recently?
Have you adjusted your idle A/F ratio?
Anything at all that you can think of (work recently performed) would be beneficial!

On my car, it would start and run poorly. Then as soon as it was up to temperature, it would die and not restart.
The problem: BAD primary injector.
Check your injector's resistance with an ohmeter. They should all be nearly the same resistance. If you have one that is much higher than the rest, that is your bad one. On my car, one was several thousand ohms higher than the rest
I replaced it with a spare and the car ran pretty good. Then I sent them off to be professionally cleaned.
The other thing I would check is the water thermo sensor, AKA Coolant Temperature Sensor. This could also cause this problem. The ECU has a fuel correction map based on the temperature signal received from this sensor. If it is faulty, it will deliver the wrong amount of fuel.
Hope this helps you
