Start up problem

[Grimm862]

When i start the car up its getting so much gas that it wont idle by itself and dies if i dont give it throttle. Whats casuing it to run so damn rich! Also the car runs shitty at 1500 rpms ONLY! Like if im coasting in 2nd when the rpms get to 1500 the car bucks like a bronco then under that its fine or over it its fine.

Just changed the plugs to supers also. I pulled the plats out that were in there and they looked fine but the car still runs super rich.

Souds stupid, but check your coolant temp sensor. If it's bad it'll cause start up idle problems.

Would it cause to the car to run really rich?

Have you checked your cold start valve? Check your fuel pressure and the regulator, if it's too high it'll cause it. check your injectors make sure they aren't sticking open. and check your afm to make sure it isn't binding or sticking.
It could also be a weak spark, or possibly the timing's off.
