Here's the deal. I'm trying to get everything squared away and back to reliable/driveable condition on my Turbo II since it sat for a year while I took care of other business. Once it is 100% I can go about selling it to purchase the FD!! I would rather not sell it as a basket case.

THE SYMPTOMS:
Intermittent hard core hesistation when the throttle is applied (1/2 - full throttle). Does 1 of 2 things when you give it some gas :
1) Goes nowhere fast and backfires, sometimes will not hold idle.
2) Acts totally normal and goes into boost.
Hi Folks,

I bought Vince's car yesterday, and I'm scratching my head about the hesitation...He said to send the RTek 1.7 chip back in for a reflash...Other thoughts?


I'm afraid to full throttle it until I sort this out, as the engine has less than 20K on the rebuild.

This is RPM independent 2-4KRPM. Thought it may be fuel related, so I drained the tank, which was clean and I had put stabil in prior to storage. Put 10 gallons of 100% gas (no ethanol) 93 octane in. Same results.

Now when I brought it back from a testdrive, it stalled, and I heard clicking from a relay and narrowed it down to the Fuel Pump Resistor Relay behind the passenger headlamp. It continued to click even with the engine off.... That is as far as I got because it was dark and raining. So that would explain the hesitation if the fuel pump is not a full battery voltage, but what would the cause be? TPS out of adjustment? Pressure sensor bad? Knock Box?

Any help is appreciated,
Vince
