buddy of mine has a 1988 BII with 2.9 w/auto trans
and 140k on it

IAC....TPS....coolant temp sensor have been replaced

the problem is that it won't idle....accelerating from a stop it wants to fall on its face and it spits and sputters.

once it gets up to speed or just give it more than 25% throttle, it has zero problems....runs like a champ

its just at idle it seems that is running way too rich and we can't figure out why

any ideas?
