hesitation is sucha broad statement..

could be numerous things
such as:
- injectors
- MAF
- spark plugs
- wastegate
- spark issues


and a ton of others...

start with the injectors and fuel...and then spark plugs...

Im going through the same thing!when i started it for the first time i was unable to
set the fp,it wont move with vacuum on or off no matter how much i turn the screw
in or out so now im going to switch out the injectors and see what happens. I already
eliminated the pump so i think it has to be the injector or fp regulator but the regulator
never gave me a problem before and i also have on3 injectors which ive read are junk!

disconnect the o2 sensors and set total timing *20 spout out. If that doesn't work sounds like injectors

I only stock Ford Racing and Siemens Deka injectors, there are better injectors out there such as ID possibly but I highly doubt thats your issue. Is the car tuned or at least a base file in it?

It is but relievent. On3 I have a set of your injectors a bit older. Before I use them I need to know were there ever injectors you sold that we're not legit? If so, can I look at them and tell?
