'97 Lumina Ideling too fast

IDLEING TOO FAST
Year/Make/Model: 1997 CHEVROLET LUMINA/LS
Body Style: SEDAN 4 DR
Engine Type: 3.1L V6 MPI OHV 12V; Auto Transmission
Manufactured In: CANADA

I just got this car back from the transmission shop [The pump was out in the tranny] and it is ideling really fast. I'm afraid it will knock out the transmission again. Is there an adjustment under the hood to set the idle?

I have a suspission the fast idle has something to do with vacuum leaks.
Any help will be appreciated.
Thanks HH

First thing to check would be that the throttle plate is closing all the way. Look at the throttle linkage and make sure that there is a slight amount of slack in the cable when the throttle is closed. It's unlikely to be an adjustment problem; linkage or a vacuum leak better bet (especially just following tranny work if your vehicle uses a vacuum modulator on the trans).

The transmission shop found a problem with an electric harness that goes to the transmission. When that was fixed the Idle speed came down to normal. I think a bad signal or no signal from the electrical on the tranny was the problem. Have you heard of anything like that?

I spoke too fast on the Idle being normal. Now It dies when you take your foot off the gas peddle.
I'm told I need a Throttle position sensor, an idle air control mtr, fuel filter, pcv valve and two oxygen sensors. I want to work on it myself. Do I just start replacing these items? Can I buy them at say Auto Zone. Which ones should I start with?

thanks

throttle position sensor or the idle air control motor is both items that would likely affect the idle of the car but you may want to get a second opinion or atleast have codes read and cleared before you start changing out parts
