cuantas millas por galon hace un chevi corsica 1989?
check the soleinoid
No it does not.
The idle air control valve is located on the throttle body, and the EGR valve is located on the intake manifold.
Computer controlled - not adjustable
It is normal for the oil pressure to drop when the engine is warmed up and at an idle.
either bad gasket under throttle body or bad iac valve
It's likely the fuel pressure regulator. I had a Chevy Corsica with the same problem and it was solved by replacing the regulator.
Please disregard the above question, I posted a somewhat more detailed question regarding this. Thanks
CHECK COIL PACKS
This car is computer controlled, and assuming it has the Chevy 305 it is also fuel injected. There is probably a problem in the computer controls causing it not to idle. Do not attempt to adjust idle, as it will not fix it, and may cause other issues when the innitial problem is diagnosed and repaired.
Idle is set by the computer.
For non fuel injected models, on the side of the carburetor there is an idle screw. Turning the screw slightly will raise the idle on your Chevy truck.
