Toughspot

As I'm driving with the pedal depressed an bucking action will occur at which point I release from the pedal. I'll be able to drive for another 5 minutes before another bucking occurs at which point I'll release from the pedal. All this time the transmission never achieves overdrive because the bucking is so constant. At 0% TPS I'll have to say that there is no bucking at all. I notice this as I pull from my house and drive to the highway. It takes about 5 minutes and I use this time for my truck to completely warm up as the pedal is at 0% TSP

My mechanic used his scanner at the mechanic shop

No was to track sensor data. No code errors being displayed.

I haven't noticed but I will be sure to observe... Since it happen in first gear and chances not a TC lock up issue, can it still be attributed to bad grounding?

I will definitely do this ground mod this afternoon Whenever I give throttle... But idling out to the highway through my community it doesn't happen. But yes... It happens it 1st gear.... Or as long as the throttle pedal is depressed I've already replaced the TPS 3 times

yes sir, regardless of conditions. By the way I'm in the Bahamas so cold weather not a factor. I removed the connectors from the PCM and sprayed them with electrical cleaner just in case salt might be an issue

This morning alone I was simply taking off. So my speed was about 10-15mph I will do the ground mod this afternoon after work and let you guys know how it turned out

By the way, I had this problem when the truck was BONE-STOCK... I was hoping minor mods could help

Mods on truck: 1. BANK Cold air intake 2. BANK intake elbow 3. RAPTOR lift pump 100GPH 4. CAT 2 micron high efficiency filter 5. Just added Edge-EZ 6. ATS signal conditioner Just added tuner, but the problem existed before the addition. Thought it might helped Aurora 3000 Turbo charger No other engine mods... stock injectors

Okay will do... By the way these are my VAC readings I got from the alternator... 0.012VAC is across the battery and 0.033VAC is from the output cable of alternator to negative post of battery.

I disconnected the alternator per instructions in one of your post by un-clipping the wire and removing the 140A fuse. I went for a drive and the problem still remain. So I assumed the problem might not be alternator related.

I'll try this exercise and report my results. Not to mention the alternator is new. By the way, just to show how desperate I am, I ordered the diode bridge (Order #1698) from you to have my spare alternator rebuilt to try to out.

I'll preface my post by committing $200 to anyone whose recommendation solves my issue. This is not my truck in the YouTube video but it accurately depicts what I'm experiencing. https://www.youtube.com/watch?v=xudW4yafWTc Here's some brief maintenance history on my truck: 1. Newly rebuilt tranny 2. Replaced 3 separate TPPS (WELLS, Timbos and Stock) to try solve issue 3. Installed RAPTOR 100GPH lift pump (16PSI at idle, 15PSI highway) 4. Newly installe remanned VP44 pump 5. All battery cables replaced with 2/0 7. Thoroughly cleaned engine block grounds on both sides of the engine 8. ATS signal conditioner install at PCM 9. No code errors S.O.S. I desperate guys!! Please help!!
