Re: Hesitation

If your referring to the TPS rate of change AE, I believe so.
Why would that be an issue if the tune has not been changed. Or anything tune related for that matter, if its the same base tune?

Re: Hesitation

Yes. Multiple revs resulted in no drop in fuel pressure. Some revs would act up and once or twice it revved normal.

Re: IAC opening AF 20+:1

That is an option. However, the car idled fine prior to removing the intake plenum to replace injectors. I would prefer to fix the problem if possible, before taking the IAC out of the Loop.
