For some reason my car is acting funny. I had an apexi power fc on but I sold it because I needed money. I put my stock ecu on and my car idles rough constantly jumping. Could this be because of the idle screw I had to close according to initial of power fc I did? Should I reopen open the idle screw if so how much? I would like to get some hands on help if anyone know any shops in the area I can go to if I can't find the assistance on here?

 

Check your tps and timing, adjust it to where it should be that could be your problem.
