There is a idle screw on the throttle linkage on the carb that you can turn to increase the idle speed and then hook up your timing light to check the timing.

How do you adjust the idle on a fuel injected 89 Pontiac Sunbird?

If your engine is ideling fast its probably temperature senser. There is no adjustment for idle. that last answer is not entirely true. u can adjust the idle. but it depends on if its a throttle body unit that looks like a carburetor or a smaller unit. on a TBI unit, there is a screw u can adjust but the only way to adjust it is with the right tool. its not a Philips screw or straight blade. but if its idling high or fast it might be the idle air control valve. the one went out on my 1985 sunbird and caused it to idle funny.

There is no way to adjust the idle as it is controled by the computor. You either have a idle control mod. bad or crankcase sensor. Talk to your parts store and they should be able to give you some advise also.
