Install a Professional Products Throttle Body today, now the car runs like crap. I don't know what's going on but it acts like I have a large vacuum leak in the intake.
First issue I ran into was in the instructions. It says to adjust the Idle speed screw counter clockwise until the throttle body butterfly is fully closed Then continue to turn it until you get .010 clearance. Once done, turn the screw clockwise one full turn. If you follow those instructions the throttle sticks because the butterfly hits the TB throat and slightly jams. I have to turn the screw another 1/4 turn to get the proper clearance.
The second issue (which is the biggest) is after adjusting the TPS to .925 volts I start the car and it idles was up in the 2k rpm area way to long. Then after about 15 seconds or so it finally drops down to about 750rpm. If I rev the motor it hangs in the 2k rpm area again and then drops. It makes the car very un-drivable.
Anybody know what's wrong? I had to fall off the new TB and go back to stock.
