Yeah if the car won't go over 2500 rpm it's almost always a maf or maf wiring issue. Unplugging other sensors won't cause the car to stall unless you unplug the distributor or enough injectors to starve fuel.

Step 1: verify that your maf wiring is good. This might be as simple as a shitty or corroded connection. You can get electrical terminal cleaner at autozone, and a wire brush or toothbrush.

okay so i recently looked at my chassis harness and noticed a lot of stuff has been bypassed and hacked up so im just going to replace the harness and noticed my dash harness also has been hacked up too so ill have to replace those and hope that fixes the problem. also i had a question about will a dual cam chassis harness and dash harness work on my 89 s13?
