I do in fact. I'm not sure if it's in the truck but if it is I'll hit the freeway on the way home and snag some data and report back.

 

Too easy.

Post up what ya find.

 

Just realized I can only select up to 5 live data sources; I imagine I'd want MAP, fuel trim, engine load, bank 1 O2 sensor 1, and bank 2 O2 sensor 1?

 

I would look at MAP, TPS, Engine Load, and fuel trim..... Long and short term.

 

The higher speeds are literally with the pedal on the floor, so potential TPS malfunction? A bit odd if that's the problem since I have no codes of any kind.

 

If that's with the pedal on floor, then TPS is WAY wrong. Everything else looks pretty good. Aside from engine load.... but, given TPS is just flat out wrong..... not a surprise that one isn't exactly accurate either.

 

Yup, pedal all the way on the floor! Another new TPS it is..

Any idea if the NTK ones are any good? The only Mopar ones are like 5 times the price through 1A Auto.

 

OE Mopar is best to use for the TPS sensor, if at all possible. Use the part number and Google it. Sometimes, dealers sell them as overstock on eBay, too. Rock Auto also sells Mopar OEM parts.

 

TPS isn't as critical as say, the crank sensor.... I used an aftermarket sensor on my V-10, and it has worked out OK so far...

 

I received the Mopar TPS sensor in the mail yesterday, installed it on the truck, and took it for a test drive. These are the scanner readings during my drive. It appears that at idle my throttle position has decreased by 4% or so, but after letting it idle for a while the RPMs began to drop below 500 and it started stuttering. I gave it a bit of gas and it corrected itself and the issue didn't present itself again. At highway speeds the throttle still won't open up past 64%. I looked through all my old receipts and it appears that my crank sensor is a Duralast model; I swear I had replaced it with an OEM one from ebay as I have a spare crank sensor that is virtually brand new, but I couldn't find the order confirmation or receipt anywhere for anything other than the Autozone one.

I guess my next order of business will be to order an OEM crankshaft sensor?

As a (relatively) uneducated guess, I wonder if there's any issue with the air cleaner since it seems like with the engine isn't getting enough air; I've already replaced the accelerator cable and confirmed that the throttle body has full rotation and operates as it should (to my knowledge), so if it is all the way open when the pedal is fully depressed but I'm not getting full power there's a restriction somewhere. The passenger side fender was replaced when I originally purchased the truck as it was damaged, and if I recall correctly the truck I pulled the fender off of was a 3.9L V6. The hole in the fender where the air cleaner connects to was the same size, but I'm wondering if internally the structure of the fender is different based on the engine size, so being that mine is a 5.9L it isn't getting enough air. I haven't opened up the air cleaner to check the filter but everything is new and the truck hasn't been driven more than ~200 miles since the filter was replaced, and I didn't drive in any conditions that would've clogged it up.
