my friend recently swap a gsr in his 94 coupe. Car runs fine but when he full throttle the rpm goes slow, whats the problem check engine light is on but i havent check, doing it today.

 

Will the situation is he dont have a comp and the car is not outside of my house. So when i go to help help fix it i have to drive a bit to get there. I just wanted suggestion before i go there and work on it again. Plus he dont know how to read the flashing light so that out of the picture if you want him to tell me what it is and for me to search.

 

Without knowing what code the ECU is throwing to light up the CEL, you won't get too many answers. Jump the connector and pull the code.
