Thread: problems with g20 staying running

I got a 95 g20 been running off and on like shit. Somedays it runs good and then just the opposite. It seems when its wide open its good and at low r's it wont stay running. Ive recently replaced the plugs and wires, fuel pressure regulator, and maf. The car was no cat and make shift short ram air intake. I believe its the air temp sensor that isnt plugged in. Im on the verge of replacing the fuel filter but lmk what wveryone thinks. Thanks in advance!
