ATTENTION 91/91 Camaro's with TPI 305 OR 350
I need you guys to do me a HUGE FAVOR!
With the car cold, start the car and report:
1. Year
2. Model
3. Engine (ie. 5.7L v8 350 TPI)
4. AT IDLE: What is your TACH reading?
The reason I ask is because my 1992 Camaro Z28 (5.7L V8 350 TPI) idles at 10,000 and a friend of mine who owns two 1991 Camaro Z28's with stock 5.0L V8 305 TPI engines claims my 10,500-11,000RPM (at idle) is WAY too high and claims it SHOULD be around 8,500 - 9,500 or so..
My mechanics have ALWAYS had the car idling at around 11,000RPM during cold and I don't believe it go down much more when warm.

umm I think you got 1 too many zeros on that,
rpm vs coolant temp straigt off 91 LB9 auto
600.00 152*C
600.00 140
600.00 128
600.00 116
600.00 104
600.00 92
600.00 80
700.00 68
700.00 56
800.00 44
800.00 32
1000.00 20
1000.00 8
1000.00 -4
1200.00 -16

depends on coolant temp if its 30*C outside its going to idle lower then if its -8*C,
but I don't think thats a factor until O2 is warm,
whats the big deal about idle rpm anyways?
there is an adjuster screw, that shouldn't be touched buit some time does over the years

1. Year /1987
2. Model /IROC
3. Engine (ie. 5.7L v8 350 TPI) /L98 TPI 350
4. AT IDLE: What is your TACH reading? /1,050RPM
Your good at 1050-1100 for a couple minutes. Mine drops rapidly to 650 after that.
