Just bought a 87 w/ rebuilt motor, rb header, rb aftermarket mufflers ect. The car hadn't been started in a month when i picked it up and only had a 1/8th a tank of gas in it when i got it. Trade in at local dealer. Anyways the car feels like it's getting too much gas and stumbles a bit under extreme acceleration. it had a quick puff of blue smoke on initial startup but it went away after it warmed up for 1 minute. the oil pressure is at around 40psi under normal driving. but it feels bogged down over 5.5k in second gear and the idle is a little rough.... up down up down .... I havent replaced the plugs, wires, fuel filter yet or run an injector cleaner through yet but i will do so tommorrow. Any ideas on what's wrong with it? could it be the things i said? Let me know this is my first 13b i always have messed with the 12A's

 

Idle problem is probably a misadjusted TPS.

Blue smoke on startup isnt anything to worry yourself with, its fairly normal. If it smokes ALL the time, then I would get concerned.

 

how do you adjust the throttle position sensor?

 

What J-rat says.

Do the basic idle adjusting procedure + TPs. A full tune-up would not hurt either.
