Stumble with 50 lbs Inj.

[NTMD8ER]

Well got back on thursday, took the car back out with fuel psi at 50, car ran fine but rich, started lowering the pressure buy 1 psi till I got it down to 45 psi line off. problem is gone. must have been some dirt or debre in the gauge or regulator.

Thanks for the help.

If the Injectors are purchased from PTE they will have flow data
etched on the side of the injector as well as a serial # and date:
We test the injectors at 90% duty cycle for several reasons, and we also ck them at static from time to time.

Our test runs about 3 to 4 min on each injector and if you hold the injector static that long it gets hot.

We sort the injectors after testing and match them up by size so you always get a matched set from PTE.

Most 50 delphi injectors flow between 51.5 and 47 pph static. Yes we agree that is a big range ... Thats why we match them BEFORE we sell them. I can ck the # if you call me on saturday at work

Is it possible the IAC needs to be rest for the new chip? Have known this to cause off-f idle stumble from time to time

Good Luck
