hey guys
I've just switched my 1988 TBI Fbody to 1991 TPI. Everything started up great. Seems to be pretty responsive... But yet I have my engine light constantly on... then after turning the engine off and just turning the key on I can't get the codes out of the light when I jump the two terminals at the ADL port. By the way I'm using a SD harness from Painless. I'm figuring it's something to do with my Map sensor... I'm getting a lot of black smoke during idle. I've got everything alse on the car to work so far- haven't been opn the road yet to try my cruise control though...

Any other suggestions?
