Everything was in order. I dummy checked and triple checked. All the weird stuff happened after but when i took it out the odd stuff stopped. My car is back to normal just when i put the part in is where it happen. By the way the spacer is 5/8 thick and the gasket is 3mm or 4mm.
So i received my throttle body spacer and my engine made a knocking sound when i start the car. also all the pedals were shaking.. When i took the car for a drive it felt like the car wanted to shut off...Any idea why then would happen?
