1986 GL-10 Turbo Wagon, FWD, 3AT. Ok I finally got the wagon back on the road after a suspension rebuild and ignition tune-up. The car runs fine except for valve train noise that I plan to tackle with some SeaFoam over the weekend. The only annoying issue now is that the cars idles a little low (around 750 RPM on the digital dash) when I'm sitting at a stop light in with the 3AT in the drive position. I'd like to get that fixed. Any ideas? Thanks. ./steve

Shift into neutral?

 

Well, seriously, what is the idle RPM in neutral? Not that *I* could help with an analysis with that info, but I bet others here could.

Ok smarty - I actually have started doing that! Idling in neutral is around 950 RPM closed loop (in spec from what I read). ./steve

There is a screw to set minimum idle, look by the throttle arm. 750 sounds fine, isn't the spec 800 for AT?

I didn't realize there was a throttle adjustment for MPFI.

 

I wouldn't be worried about the 750 RPM - as you said 800 is the spec - but the engine really chugs when things are going this slow...it sounds like my subie is really gasping...
