So I wired up my power windows today using relays and decided to take it for a test drive. Everything went good tell I put my foot in it a little, maybe 3/4 throttle. Then a hear a pretty loud crack and feel a little vibration at the steering wheel. The engine also cuts out for just a second. Afterwards it drives just fine. Recreated it maybe 3 more times trying to figure out what is happening.
Anyone have any idea? or where I should start looking? Never has done this before. Noise sounds like its coming from up front.
Its a C20 with the 454 and TH400 tranny.
Did a visual inspection once I got home, found nothing out of place.
