okay i swapped a 91 LS motor into an 89 civic DX, everything is wired up good, but it idles like it has a bad IACV but no check engine light and i even blocked off the two holes in the throttle body because it was the only way to get it to come down, worked for about an hour then it starts doing it again. all the vacuum line are hooked up, but im not sure if they are exactly correct, im still runing the dx MAP sensor, any suggestions????
