Update! Compressor went out:mad:. Took it off and it seems that there was no oil within the pump. Haynes manual says to pour oil out of old one and pour into new. When i did this, , nothing there. Thanks y'all for your feedback. check that oil in the compressor, i got hit with .

Revised Response!No codes. Checked the alternator using the Haynes manual method for testing. Alternator seems to be fine. I read the thread posted from rooster (TC lock/unlock issues) and followed the video you posted. My DVM was measuring 13.97VDC and 30 VAC. It appears that the score is tied. I guess the bench test is going to determine the winner. . I will keep ya'll posted.

the low side was about 106psi? does that sound right to you? maybe compressor is out?

Sorry i was late for class. can you please explain your battery troubleshooting results?

, man what you had described was and is what is going on with my truck. i was hoping it was something different than the solution that you had posted. I have new batteries and my issue has not gone away. I am thinking of having the alternator tested per mrtowman's previous experience.

Thanks for the response. I am getting the occasional dead pedal above 50 mph. I did a boost leak pressure test, which the results were negative on any leaks. Fuel pressure is about 12-15 psi WOT, with no drop in fuel pressure when i get the dead pedal. I hook up a scanner and get no codes. Anybody ever have issues with calibration screws or spring of the APPS assembly?

My issue started about a month ago. Up until last month i was able to Idle the truck with the A/C on with no problems of humidity within the cab. I am having the issue of not being able to cool the cab. The A/C clutch is working because i hear that thing engaging a block away:lol:. I start to drive the truck around and A/C comes back and starts pushing cold air again. Has anybody had this problem?

Does anybody have to reset the Timbo Apps on a Bi-Weekly basis? It has been happening now for 3 months. I disconnect battery for about 2 hours, then i reset the APPS and truck runs fine, then two weeks later i am having the same issue. Any feedback would be appreciated

i am due for the test this week. a couple years ago tech told me that they only make sure you haven't tampered with stock system. this is why i don't do mods. oh yeah and thats how they justify the registration charge by taxing you on how you pollute the air. there is no way to smog diesels, due to not having catlytic converters.

When you first tested booster, was there a loud shrieking sound? Is this normal? Is this the wastegate actuator?

Well, it took the boots that come from the tubo off to inspect for cracks or pinholes. No dice. I noticed oil within the boots. Is this normal? I reassembled and cranked it up. Noise was gone.. I will check back in tomorrow.

Cummin Dodge, did not mean to hijack your thread.thank you all for your input. Noise is coming from where the aftercooler is.

That sucks man. where were you at when this happened? I live in Pico Rivera. Did you have it towed to your house?
