I just got an awesome deal on a 90Iroc l98 350tpi auto, anyways the car needs a little work but it feels like its not at its fullest potential. This weekend I am going to do a full tune up and see if that helps, I am going to do new plugs/wires, cap/rotor, air filters, check timing, flush radiator, service tranny and you know all the stuff when you first get a car anyways. This is my first fuel injected car so I was just wondering if there was anything I should know that would be robbing some power other than the obvious.
thx.

 

I'd replace the fuel filter, change the serpentine belt, and get some Berrymans B12 Chemtool systel cleaner. Replace the PCV valve and do a good inspection of all the vaccuum lines as well.
Yeah, fuel injected cars can be a big PITA, but when they are in sync, they'll run like a scolded dog.
