hesitation problem with new tunes pls forward bill

[epowers777]

I tried that and nothing different happened. Do you and bill remember my computer problem I had were we couldnt find the code on it. It was xx do you think maybe that has something to do with this.

Nothing different happened....What does that mean? Does it mean that it still hesitated and tried stalling with the chip removed?

Nothing would be affected other than a check engine light due to improperly working glow plugs (due to your truck having a glow plug module) if you were sent the wrong PCM code......and you have no diagnostic trouble codes so we won't even worry about the wrong calibration code.

Nothing happened meaning the code reader did not pick up any of the sensors. When I unplug the chip it runs horrible because of the single shot stage 2 injectors so I could tell a difference. BUT I got an update Cody.
I took out the ipr regulator and cleaned it,

There is the link I found. Here is what I found.
The round magnet thing was not bolted down on the ipr regulator. It was just sliding back and forth. So would that cause an issue? I pulled the reg. Apart and cleaned it. I searched and found a pipe reducer that fit on the screw part on the reg. So I re installed the regulator put the magnet thing on, a bolt to take up space, and then tightened the reducer to hold everything into place. It's ghetto but it works. I drove down to auburn (430am) and back and no hesitation. Its still cool out so this evening i will drive it to test in the heat. Hopefully its fixed. Any comments?
Going to bed been up all night! Nighter

Good find!

I have always wondered if there was a "IPR mod" that would get rid of that stamped nut and use and actual locking nut.

Uh.....yes.

I am willing to bet that your issue is probably fixed.

Eric,

We at the office are wondering how your truck is reacting with the IPR solenoid "fixed". If you have any other questions or concerns please let us know.

We are hoping for closure.

Sorry I havent called got a lot on my plate. As for the hesitation problem it has seemed it has disappeared. The idle seems to still be a tad ruff. I am waiting for the new sensor to come in. If that doesnt fix it I will post again.
Thanks for wondering.

Just be aware that single shot injectors normally will be a bit rougher than splits, and a bit louder too.
(They don't have to be but without live tuning every truck will be a bit different.)
