idles at 20-22 AFRs no matter what I play with in the 'idle' area of the fuel maps...

after a drive (brisk or not) coming to a stop idles high (1250) then ever so slowly creeps down to about 500-600

also, the ~0 Vac lean spot i have been seeing is more prominant in NG5-5

I also picked up a PR4-A10 for my 91 teg and this might cure what ails me as well.

im on jackstand right now tho, so testing is halted (axle boot own'D me)

I'm now having Idle problems. Sometime real low (500rpm) and some time revs wont drop when I let off. They drop to 1100rpm until I tap the gas again. AFR, I don't know just know that theyare REALLY rich! finishing WB this weekend so I find out exactly. Spits alot of black smoke since I changed and sputters at idle and backfire alot when I let off the gas.
