I think the fuel pressure sounds like the culprit, check the pressure with a
guage and see what happens. Does it want to give out at long hill climbs and
the thing wants to choke out? Also, the idle will drop and stall at stops.
This could be the problem. Check the alternator to be sure its running at 12
volts. Make sure the grounds are good on the ECU connection and engine
grounds are good. If the check engine light comes on, check the codes for
EGR and check the control valve for the EGR that has the 2 vacume lines
running from it, check the ohms of the harness end. 2 points, check that.
Do you want the instructions in full?
