Hey there!
So I have begun using Tunerpro RT to diagnose my completely stock 93 gmc c1500 350 4l60e and figure out why I am getting a rough idle in gear and after checking vacuum, it intermittently drops 1-2" when the rpms drop.
I understand what like the sensors should be (except the map sensor because I thought if it has 18" in vacuum, it would have about 60 kpa which it registers around 30 to 40 at idle. also I just checked to see if it held a vacuum and it did).
Anyways, is there anything that i should look at closely when the engine hesitates on the datalog and explain to me what the engine should do to run perfectly via the engine senors, blm , intergrator so on and so forth.
looking at all these inputs the ecu is giving me is all new and alittle more complicated since I am so used to using carburetors.
thanks guys
