Need Help with stumbling
Hey all, I've been trying to solve a stumbling problem with my car, I have an 88 305tbi. I've already changed the MAP sensor, TPS, rebuilt the tbi, and checked the wires, cap, rotor, coil, and plugs. When the car is running, it jumps from 600 to 1200. I can unplug the MAP sensor and the car will idle at 1100. I was wondering what else might be causing it to stumble, thanks in advance

When you unplug the MAP sensor are you unplugging the electrical or the vacuum line.
