Re: Fuel Issue
Vacuum could certainly be a problem to look into. What is your timing at? Did this problem start after you swapped the TPS? DId you check the voltage on the TPS after putting the new one on? Have you tried pulling any codes? How old are your O2 sensors? Also you didn't mention what year your car is, does it have any other modifications, tell us some about your car to help diagnose or guess (lol) your problem.
