Man it a wild goose chase for you... I don't think the ECM is the problem though...

Well APPS sensor when it fails it will ALWAYS throw a P0121, P0122, or P0123 error code... Since no error codes are present then it most likely going to be you VP44... 8| http://www.bluechipdiesel.com/vp44diagnostichelp.html

Still no codes? :confused:

I swapped out my Big O AT tires (235/85 R16) for my offroad Cooper STT tires (265/75 R16) and lost -4 MPG's just heading down to Ontario, OR for my front ABS sensor being repair. I dropped from 21-23 MPG (Big O AT) down to 16-17 MPG (Cooper STT). Tire a huge impact on MPG's...

Good ol' Idaho people are helpful... ;)

I played with the downshifting... I got mixed results but most of the time downshifting is a bad thing. As soon as the RPM's pop up the MPG's fall again. Remember you got to fill the cylinders with fuel yet and you Revin' faster now at the same speed so MPG head down... But strange that SPEED is the number #1 killer...

Here you go... http://mopar.mopar1973man.com/cummins/2ndgen24v/apps/apps-replacement.html

Check for error codes.P0121, P0122 or P0123 is a APPS failure...P0216, P0251, P1688, P1689 is a VP44 failure...

You could try Caspers Electronics that is where I order my plugs for the high idle kit I built... http://www.casperselectronics.com/store2/

What not just buy a Frantz filter... :confused: Built right here in Nampa, Idaho... :confused:

Yeah another thing to think about that Dodge's crankcase gasses are vented out to the atomophere... So crankcase gasses shouldn't have any effect... :confused:

Dorkweed should be able to tell ya... :thumbsup

One of these days I get to look at a 6.7L Cummins to see what all the stuff is... As for EGR system most yank it off and plug it...

sometimes it will dribble back along the drain tube to the firewall and seep back pass the foam seal to the carpet inside.. The solution is to extend the tube down and away from the cab... ;)

I agree with Russ... My straight pipe is rotting away in a rapid way... So if it rots away I'll be looking for a full 4" exhaust system next... :rolleyes

Like myself I'm also running petroleum based lubes in everything and pulling 21-23 MPG which happens to be highier than most... So why waste the extra money on Synthetics when I'm beating most rigs that use it... :confused: LOL

Hmm... Ford and chevy both got crankcase vents into the inlet of the turbo...I've seen another setup where the crankcase vent was plumbed into the exhaust stream and burnt off in the pyro heat...

I would say the general public is just holding there own... But we are getting smarter than them. :smart It seem like I run rings around most people out here. I just had a vehicle that was broke down yesterday in New Meadows, ID I pulled up and walk over. Just looking at the amount of engine oil pouring out on the ground from the radiator cap my first reaction was "Your head gasket is blown!" :wow The owners reaction was "How much do that cost and can I drive it to Boise, ID to get it fix?" LOL Like I told them the farthest that vehicle will go is from the median to the next side street about 100 feet...

I heard the same thing... BioDiesel and DPF don't mix... As a matter of fact not only Dodge has the problem but VW wrote a article about this too...

Typical of you Flagman... LOL :thumbsup Well out here in Idaho I'm hoping that there isn't much for fireworks. Grass is getting tall and dry... 8|

I don't know for sure but they might? :confused:

Check the trans relay in the PDC to be sure its not bad... :confused:

I'd say get smaller injectors 75 HP and then throw a enhancement box like Edge on there and that will give you more control over the fuel curve.

I guess so.. :confused:

This is one of the reason why I started my own business... I been there one time long ago... don't ever plan on returning to that... 8|
