I just bought a stock 87 gn it has an aftermarket intake which is not labelled. The cars idle fluctuates I don't know howuch because the tach is inaccurate. Also if I hit the throttle hard off the line and then let off quickly the idle will drop right down and it has even stalled on me a few
times. Driving normally the car feels like it shifts fine although it does have a slight hesitation off the line. I'm thinking a scanmaster will help me diagnose what's wrong here and help me tune this thing up. I forgot to mention the car has 136000 km and has a pretty new water pump new plugs and wires a new fuel tank and a new Bosch fuel regulator. I'm not sure if the pimp was changed or is stock this was all done by the previous owner. Any suggestions would help I will post pictures of it tomoro that might help out
