Still have problems. Car starts hard cold, 2-3 5 second cranks to get going. No stumble/hesitation once started, but after 10 minutes, get the stumble/hesitation off/on, but defininately get it on a hard right turn. Here's the list of things done:
New Control Pressure Regulator
New Crank Sensor
New fuel filter
new FI relay
Checked/swapped radio surpression relay
Removed/cleaned Throttle body
Removed/set up throttle position switch
Pulled tank pump- new filter, good bellows hose, pump seems good
Pulled main fuel pump- seems ok, check valve seems ok
ran Chevron Techron FI cleaner through system
Any ideas? Got to get this hesitation problem fixed by March- Daughter starts driving ;(
