Re: Hesitation in 3rd and 4th (please help!)
When you set the TPS voltage did you set the idle first.
Unplug the IAB and set your idle, set your TPS voltage , then hook back up the IAB and turn off ignition and disconnect the neg battery for @15 min to reset the EEC.
Might have to do this a few times.
Curious if your TPS voltage changed from where you just set it.
