ecm 730 91 camaro prom sf512 I have a problem i have noticed that every once in a while it likes to come up to stop sign then u press the gas and it wants to die and every time then ses light comes on.
So i went home to hook up to tunerpro and started put in drive started doing it again so i looked at tunerpro and here goes
map volts 2.68
map kpa was way high like 80
my blm was at 160
Now it was still in closed loop and my blm was never 160 it was the oppiste at 108 at idle way to rich. What the heck is going on here
Now my car is fine intill it does it again it has done this before i started programming
Please help

 

I would look for a vacuum leak in the map sensor line, 80 kpa is like no vacuum. 100 kpa is 0" (WOT), 80 kpa is 6.3" (heavy load), and 35 kpa is 20" (Idle).
