There's got to be a solution??? (THERE IS, PROBLEM SOLVED!)

[iamironman]

I will try everything suggested... but... is there a way to adjust the rich/lean? Or is it totally controlled by the MAF/ECU? Or other sensors communicating with the ECU.


THANKS!!

I am probably speaking out of turn here.. but I think the only way to adjust the parameters is with a computer and isuzu software. These don't adjust like a carb.

good luck

I thought so... thanks for all the info. I ordered the FPR and MAF/MAS... 'twill be here tomorrow...

[iamironman]

Ok, it was the FPR!!!

I got the parts in and first tried the MAF... for obvious reasons... it was easier... NO change... still 'idle surged'... left the MAF on... new fuel filter... NO change... so I put the original MAF back on and did the FPR... WORKED like peanutbutter-smooth n creamy.................
perfect idling, perfect acceleration-WAY better pick-up, just all around smoother in EVERYTHING it does... so I put the new MAF back on and it seemed to do even a little better... (the onl reason I switched back to the orig MAF was troubleshooting 101, eliminate all possibilities to see what the root cause is).

Thanks for ALL the input... I think I'll keep her, she's muh huckleberry

Way to go, dude! But wait, you didn't tell us how much fun it was to change the FPR!

PS - Stick a new EGR Valve on and I bet it will run ever betta! Like butta!

EDIT: How was your old FPR? Mine had several small holes in it when I changed it out.

I didn't think it was all that bad... I downloaded the PDF file from this site... cutting the allen wrench with my dremel was a breeze... for the replacement bolt I just switched with a bolt from on top of the intake that was holding down a bracket... same size length and thread and used that to replace the rear allen head bolt. The circlip was easy getting off a lil more difficult getting back on the new FPR as it seemed to sit a lil higher than the old one... prolly the newness of the new o-ring. Whole thing took 20-25mins.

Overall, changing MAF, fuel filter, and FPR took hour and a half, tops.


Old FPR?: it just looked ooold n worn out, no visible damage or deformity
