pretty much what the topic says,what can i do to raise the RPM's up to 700 or so where they should be? its a 87 IROC w/ a TPI. thanx

 

I wouldn't rely on the Tachometer competely to adjust your RPM's at idle, but if your car is idling so low that it lopes, then you can do a quick adjustment to the throttle plate stop. On the driver-side of your engine, at the Throttle body, if you look from the back of the throttle body towards the front of the engine, you'll see a recessed screw on the top-driver side corner. This takes a T-20 (maybe T-15) Torx bit. Simply screw the screw clockwise (tighten) until you are happy with idle.

 

my car idles about 550 when im in drive, it's perfectly smooth though.....never stalls...should it be higher? i just figured lower RPMs at a redlight means better gas milage....
