How do I increase the idle speed on my automatic 1984 crossfire corvette?
Any help would be appreciated.

Thanks

Pick up a Haynes manual as the procedure might be tricky.

I believe there may be some sort of balancing opertion involved on a X-fire.

 

You shouldn't have to mess with the idle speed on a crossfire, Its controled by the ECM. Try setting the TPS and clean out the IAC...go here it will show you how to do it.

Why? My crossfire idles around 900 when I first start it up and then comes down to 600 when warmed up. I wouldn't want it to idle at 900 all the time.
I have an automatic also. At 900 I would have to really mash the brake to keep it from creeping forward when stopped. It idles smooth and the flowmasters sound great at 600. Just my opinion.

 

put in a 383 stroker! :jester :p: no seriously TPS will change idle. :yesnod: good luck.

 

THANKS FOR THE REPLY..

REASON WHY..


I put on march pulleys....also installed a true stuff altenator 140AMP.
But still when the car warms up..and I put on the radio, or air conditioner,
and then apply brakes charge goes int red zon 11.4volts on dash..

that is why I thought if I increase the idle higher it would help...even when I hit the brakes the voltage drops...let alone trying to use the radio....

I have installed MSD coil....K&N FILTER....FLOWMASTERS....ETC.ETC..ETC...

what do you think

thanks

Thank you

but what is a TPS OR IAC Cleanout?????

High amperage alternators "in general" do not pruduce as much current at idle as stock.

Loose the alternator and get your old stock rebuilt at a local shop.

 

TPS= Throddle Posision Sensor
IAC= Idel Air Control

Removed the March Pulleys...everything OK....NOW....

MISS USING THE PULLEYS THOUGH....this was 2 set....crank and altenator...
car even runs cooler...
