Did you get a chip tuned for it? I know the stock 94-95 computers dont play nice. Also do you have a pulley kit in it? If you have underdrive pulleys try putting the stock pulleys on first. If you still have the issue get a chip tuned for ut car.

Clean out your IAC with some carb cleaner.
If you dont know how, google it.
I have no idea what the code means, but usually you can clean out IAC and it should help you a little bit. Theres alot of grime that builds up in there.
If that doesnt work, it could be a faulty TPS.
And if not that could be your vacuum lines, make sure there's no cracks in your intake hoses.
To check for a faulty fuel pump, take it out, attatch it to a battery, sit it in some gasoline and see if it flows. If not, there's your problem.
Oh, and have a friend with you to remove the tank. That's the one thing I HATE doing.
