I searched but couldn't find anything that could help me. Okay i just broke in my built motor. Now since i got it back from the shop its been idling wierd. When the car is warming up it idles to 1.5k and back down to 1k and the oil pressure is going up and down too. and it even does it when i'm driving and i stop at a red light, right when i stop idle goes up to 1.5k and back down too 1k. Could one of the reason be that my car is tuned right now to break in? I'm going monday to get it tune properly. thanks for the help guys
