I just did my swap and I'm getting no check engine light... generally this is good... but when I first did the swap I left the map sensor unplugged and I didn't get the engine light... why?

I think maybe it's wiring... the light never comes on even when you turn the key on... is this ECU controlled?

I did a manual obd0 to obd1
p28 ecu
car was originally pm-5

Also my L3 si tranny is giving me some trouble...reguardless of gear, direction, or speed - everytime I shift and properly release the clutch the car "jumps" like I'm dumping the clutch too fast

I adjusted the clutch (both ways) to try and resolve this. It failed to fix it.

I am now leaning toward the throwout bearing being a little sticky... I just want some other ideas...

this tranny has been sitting for a year... I didn't do anything except change the fluid before driving it... any problems from that?

suggestions to help me resolve this "unhealthy" tranny and no code ecu would be greatly accepted.

thanks guys/gals
