i just did a dpfi to mpfi swap and the car runs great but when you first start the motor it'll idle at 2000 then when it worms up it idles at 750. is this normel or do i have a problem.
also i am getting a cel that comes and goes. but theres no ecu codes.
the cel will not come on when the car is just sitting and running. only when you start to drive it. anyone have any ideas.

 

Thats pretty normal. Cold idle will always be significantly higer than warm idle. This is to help the engine reach operating temperature quicker.

 

just did not know if 2000 was normal or not. just seems a little high
