  1. Thanks guys for the help. I'll try testing the APPS again using the link you sent me @Mopar1973Man. And I'm already looking around for another VP44. @dripley 2 oz of 2 stroke per gallon? I could try that in the meantime...
  2. It's hard to get a consistent reading as the needle is quite jumpy at full throttle but it's usually between 13-15 psi. Idk if It's normal for it jump around so much but it's generally over 14
  3. Okay sry it took so long to get back on here. I was busy this weekend & work midnights... Anyway I put all the information I could in my signature; thanks for telling me how to do that. I found out the other two codes: P1693 & P230. I cleared the codes & P0216, P0222 & P0382 are still coming up. I have a FASS fuel system & my pressure is between 14 & 15 at idle & while driving around 15 but jumps up to 18-20 sometimes.
  4. So I bought my first truck, a 99 Dodge Ram 2500 Turbo Diesel, last July. A couple months later I started having what I found out was called a "dead peddle" issue. It started losing power & not accelerating as I'd press the throttle down. After the rpm dropped so much I'd get the power back & it would start screaming up the road (as I had the throttle pushed down signicantly). As it started getting cold I noticed it got worse. I'd lose power after driving up the road a few hundred feet & wouldn't really get it back until the truck warmed up. Some have said it only affected it w/in a certain range but mine did it no matrer what, even if I had it floored. I started doing some research & found out this could be do to the APPS or TPS. So I tested the voltage on mine the other day & w/o pressing the peddle it was a .38 which is low & at full throttle was over 3.9 which I hear is a bit high. But there was no drop off in the voltage at all & I tested it a few times, which I thought was odd bc it's supposed too from what I understand if the sensor is bad. So I decided to go get it scanned at an AutoZone by me & it threw codes P0222, P0216, P0382. I think it threw 2 others but the guy didn't write those down & I forget them although I'm pretty sure they were related to the first two codes if I remember correctly. P0216 is obviously the one that worries me as it's known as the "death code". I know someone who got that code on their truck & replaced the vp44 but it only helped a few months until they had the same dead peddle issue & the code returned. They ended up finding out it was a grounding issue & the vp44 wasn't getting power from the ECM. There are other reasons I've heard this truck will throw that code & I wanna make sure I do the smart thing instead of throwing money away for such an expensive part that doesn't need replaced. This is my first Dodge diesel & honestly am green behind the ears when it comes to this. What are some other things I can check for to know for sure what needs replaced?
