When I start my car in the morning or when ever for the first time after sitting all night it idles rough but as soon as it warms up it's perfect?!!? Wth is going on here?

I'll bite....Have you checked the following:

1. Any Codes?
2. Old or New Injectors?
3. Fuel Pressure readings?
4. TPS Setting?
5. IAC Setting?
6. Timing Setting?
7. Cold Start Injector still hooked up?
8. Cold Start Temp Switch working, (the one at front of intake that controls the Cold Start Injector)?

Is the engine stock, modified, crucified.......you know what I mean.

I could go on but I won't. There's just a lot of variables for "rough Idle"

Brianbajnuth

No codes
Fuel injectors are new (I think)
Fuel pressure is 80 psi
TPS is good checked it
Didn't check timing and iac
I believe the car is running lean at idle too
And when I first start the car in the morning (it about 80 degrees here) it idles at 1000rpm and then it goes up to 1300 and runs perfect but isn't that to high?
When I drop the idle screw the car runs way to rough

Not stock motor
slp runners

Edelbrock heads ( crane rockers)

TCI transmission

The engine light comes on when first start up and then when warmed up and running fine **** off back.

Are you sure the fuel pressure is 80? That's almost double what a TPI should be.

Brianbajnuth

Well unless my gauge is wrong I'm getting 80 and if I try to drop the pressure it starts to idle even rougher
