Hello,
my car is a stock 1987 GLHS. The power loss light used to come on a lot and the car would cut off some times when i put it into neutral coming to stop lights. we replaced the power module and now the light only comes on if i push the accelerator to the floor when not under boost. So, if i'm cruising at 50 mph is 5th gear doing like 2200 rpm and i smash the gas the light comes on. Or if i run it hard the light comes on. Could there be problem with my fuel pump? or is it all electrical?

Any chance you have a custom calibration in there? Many of the custom cals turn the check engine light on when the computer senses knock..
