fuelcut/stutter?
#1
So ive been having a problem with my 86 gxl. I thought my problem was the 3800 hesitation. But im thinking its something else. So here is the problem, when i go and drive the car it only goes up to right around 3000 rpm then gets louder and has a very hard time gaining more speed/ rpm. then when i let off it backfires. The problem is only under load. it free revs very nice. when the problem happens it feels to me like a fuel cut. At one point i took off the intake and checked both primary and secondary injectors. They were both priming the system. After all this i thought it could be my ports. so i ghetto wired them open just to see if that was the problem. it was not. Grounds are good. any help would be great.

Your ports arent working so youll run uber rich while the motor is expecting more air from the 5th/6th ports opening. If you can route exhaust to your 5th/6th port actuators youll be golden.
