hey i have a 88 civic wagon with a d16 y7 swap with a z6 wiring harness p28 ecu . the the car was working fine then as soon as i wired the fan switch from the back of the motor now car wont rev past 3500 rpms why would the car be in limp mode? vtec? tps? trying to figure out how to check codes aswell theres no plug for it because of the swap.
