Hi I'm new here and have an 05 mustang with a procharger p1sc and sometimes while taking off it hesitates and has a total lack of power. It doesn't do it all the time but when it does it just hesitates and when I push the gas and nothing happens but then all of a sudden it will take off and run perfect. Cruising down the rd it runs and drives perfect but from a stop the hesitation will sometimes occur. At one point after it happened I shut off the car and when I woke up the next morning I went to start it and nothing would happen. It would crank but not start. So I was clueless... But after awhile of trying to figure it out I decided to change the plugs and after I did that it started right up. But still sometimes had the hesitation issue. I just don't understand why it does that sometimes. Any ideas? I'm kinda pointing towards the throttle body.... But I changed the tpms and throttle body motor and no change. Could it be the entire throttle body? Seems like a lack of fuel. Thanks in advance!

I would check all of the intake piping to ensure there no air leak. Go through the entire inlet system and double check it is working correctly.

Have you done work on the car? If so what?

Who tuned it and has it always done it? How long has it done it? Been a weather change?

Mine had a similar issue. It was the traction control. I turn it off unless I'm driving on wet roads now.

Have you done any mods to it recently? Stock cops I hope? Aftermarket ones are horrible.
