2000 Gt Hesistation On Cold Start-up

[Joseph Ferrigno]

So the engine tapping is still there? Well it concerns me too. Is your oil pressure gauge still flaky? Could still be a bad pump or worn out lifters. A good mechanic can tell u that. Brother I would at least take it somewhere for a diagnosis. Sorry I can't be more help on it. Pearl02.

Hi Pearl02!

Update, car still tapping, and its getting worse... now on cold starts in the morning (see attached mp3 clip), it taps...very lightly though......car not only taps when going up a hill, now during normal driving.

Also, there is a slight p/s pump whine? NOT the normal Ford whine, it sounds like a groaning noise. like when i accidentally ran my p/s pump with no fluid at all...... I just got a new p/s rack installed cause it was damaged and leaking.

Yea, identified the tapping as Pre-Ignition Pinging.... cause I was running 87 fuel, but I switched to 93, and it went away a little, but I still hear it slightly...

Still have the p/s pump grinding noise under load.
