Is it a stock ecu? Place the dial on the ecu on to diagnostic mode & see what numbers come up. Remember to mark the original location of the dial before turning to diagnostic mode. Lights on the ecu - red light represents 10's green light represents 1's Tell us what codes appear.

Checked it. Got 2 error codes. One for the tps and one for the neutral switch (car was originally auto). Any thoughts? And since my last post ive replaced leads, dizzy cap, rotor button and ive checked all the connections in the engine bay
