Polished my stock throttle body today.



I installed the m113 throttle body and the car hasn't ran right since. I haven't tuned it which I imagine would help, but if anyone else has installed a m113 throttle body and had it run well let me know. It was an ebay junkyard part, so that could be the source of the problem. I think I'm going to give up and put the stock tb back. Car just isn't as happy with the mb airbox and larger TB and it started to throw a lean code.
