hey can anyone help.i just installed my rebuilt 2.0 turbo engine back in sunbird gt 89 fired right up idles fine but when i start it up the rpm gauge shoots right up maxing out but i know its only idling around 1500 i replaced most of the vacuum lines so dont think thats it some help would be greatly appreciated

Does it have a cable or electric throttle body

I am in the same boat. I just rebuilt a 91 sunbird vert 2.0 non turbo and it idles at like 3,000 rpms and then drops to about 2500rpms. I am guessing as it does not have an RPM gauge. It runs perfect but has way to high of an idle. Maybe we both screwed something up when we rebuilt them. My car only has 40,000 miles on it. I replaced every gasket on the car. It has a distributor, I do not know about yours. I replaces the cap and rotor, all the plugs and wires too.




On the inside my car looks like a fighter jet.
