i am haveing problems with the car and dont know where to start changed many parts, when idleing the rpms slightly fluctuate from around 1300 to 1700, it bogs down and will misfire in lower rpms as well. I have changed plugs, wires, distributor cap and rotor, alternator. what else should i try.?? i just bought this car a month ago drives great when after 2000 rpm and quick too. but please any info will help.

If it is misfiring and the ECU is adding throttle or timing to compensate then you are probably throwing codes. Get your ECU read first, that should point you towards the problem.

^ Kinda. Try to trace the wires from the ECU itself. It's gotta be there somewhere. Unless it was removed for some reason. When it got swapped it someone could have just been too lazy to run the wires to under the dash. I guess they could be missing completely but you would be able to tell by looking at the ECU.

They would be the wires that lead to no where or to the plug for the reader.

First off why did you swap out the b16a2 for the b16a. That is really not that much off a upgrade. Should of at least went with a b18 or k20.
