Hesitation Problem

I'm having a problem with my 98 Mustang GT. I have it superchipped and run 93 octane. I have performed a complete tune up- plugs,wires, filters and used Seafoam through the PCV valve to clean out excess carbon. My problem is when i step on the gas the car has no pull until i press down a little harder then it goes. I have a new 70mm ford racing throttle body I installed so i thought that would help but to no avail. My idle is also surges a little when in park. What could my problem be?

RE: Hesitation Problem

Idle surging could be a product of your IAC, MAM or TPS (usually).

As for the hesitation...are you running a tuned car or did you install that blower without a custom tune or atleast a manufacturer chip that came with it?

Yeah could have carbon in the IAC.... As for the hesitation the coil packs in the GT's and Cobra's are junk. I would recommend replacing them. I replaced mine becaose of this and my dads. Dan... What blower? All i see is a Superchip.
