Serious Engine Problem!!!
 

I got the UIM back on from rerouting coolant lines and installed the FD alternator on my S4 TII.. So I go to start it up and it is idling at 2200 rpm and goes up very slowly! I taped the gas to try to see about bringing it down, and it just still rose, I shut the car off after it got to 3k, then I adjusted the BAC valve then started up again, it did the same thing.... What else can I check? I am going to check the TPS right now.... any other ideas?

vacuum leak

Ok I check the TPS and it was way off the way, it was reading 6ohms at idle, no it is back to 1ohm.... So its all better now, lets hope... If not I may have a bad BAC valve...
