Ok, so here's the deal. I had a timing belt break on my 2002 Ford SVT Focus. It bent the exhaust valves in the head and they along with some shims in the head were replaced. Upon reinstallation of the cylinder head, the mechs got the car to run, but it would die upon acceleration. So, they replaced some sort of timing advancement module (I'm not that familiar with overhead cam engines so my terminology may be a little off) and it is finally drivable, but they say that it still doesn't run smooth like it should. Also, they ran the codes and nothing shows up. Is there a way to reset the computer on my vehicle? Anybody out there have any ideas on this one? Oh yeah, they said that it is getting fuel and spark (obviously since it is running) so that rules that out as well.
