ok i have an 1987 supra, 5 spd, non turbo, 7mge motor. After running for a while the motor has a hic-up, it seems to loose about 200 rpms during the hic-up. Now when driving the car bogs out between 2500-3000 rpms. I put a diagnostics machine on it and it read low ecm voltage but i cant seem to figure out the issue, i cahnged the rotor and the distibutor cap, i changed the coil pack, the temperature sensor nothing seems to work im at a complete standstill can anybody help me please.
