Shouldn't the engine rev up initially? It's like when you turn the key, the motor starts running -- but at some "limp" idle. I'm wanting the engine to fire up with a bit more idle power...then once the engine is hot...I'd like it to run as it's running now. This is an '89 and I've had to replace the 561 ECU, but the "limp" idle continued even after the ECU replacement. Kinda wondering about the Idle Air Solenoid??? I took off the whole air intake system: sprayed out the throttle plate area and the Idle Air Solenoid Valve. Not sure if it's working though...how do you test?

Any ideas???

Thanks for all your input.....I'll not fret so much.

You probably don't have a tach- most of them don't. It would be a good tool for figuring out if it's right or not.
These cars don't go into a roaring cold-start idle as most GM and Ford models seem to. I'm convinced it helps with the longevity of the car- I hate hearing a cold engine roaring away at 3000 rpm 1 second after I let go of the key.

If it doesn't stall and it's fairly smooth, I would not worry about it.
Make sure the small stuff is right, vacuum leaks, tuneup parts etc. The idle speed can be adjusted somewhat with a tiny throttle stop screw inside the throttle body. Earlier cars had the air bypass knob on the throttle, but starting in 1989 they eliminated it.
It should be working right if you can hear the throttle switch click at the closed position. If it doesn't work, the idle will drop drastically as you release the gas pedal, and then recover (or stall, if it gets bad).

Focusing on the throttle body, make sure it is clean.

My car seemed to idle the same way as yours did. After a throttle body cleaning, the car immediately jumped to 750 rpm, like it should, upon starting. (Overall, the car also ran better.)

No, My wife's '75 and many years later our '89 never idles up cold.

It starts ice cold and idles at it's 'hot' RPM. ANd amazingly enough...stays running.
