2nd Generation Dodge 24 Valve Powertrain

A couple of weeks ago, I was tool'n around town and realized my Quad XZT was on high performance setting. I switched back to the low setting which I run all of the time. However, shortly after switching down, the engine light came on. The code was P0237. Since then, I have hardly driven the truck. Today, I disconnected the Quad XZT and drove the truck to run some errands. After a few starts, the engine light went off, and when I checked codes, only the P1698(I think?) was displayed. Here's my take on this. The truck was never over 40mph when the XZT was switched to the hi setting. It was dumping fuel with very little boost, and the MAP sensor thought the boost wa…

This is part 1...... Next being adjustable track bar and traction bars both already on order. Before After Already did the 3rd gen brakes too.

Ok guys starting to save up for the inevitable tranny rebuild just wondering what all of your recommend. Myi signature is accurate except for the new air dog. I tow a 10k toy hauler and I plan on installing rv275 s and a new turbo soon. So what brand/ build do all of you recommend? Thanks

Does anyone have experience painting the valve cover while it is still on the truck? I took my truck to the car was today and degreased the engine compartment. It looks great except that the pressure blew all the paint of of the valve cover! I believe it is aluminum so there really shouldn't be any concern with rust correct? I would like to paint it red like I have seen a few. Any ideas?

I've read about the benefits of 2 stroke oil and especially2%biodiesel.Since I can't buy that in the ethanol state CA( surprise !!! )how about cannola oil to lube that CP3 ?Thanks Hanno

I can really hear my fan when it's really hot, but I'm wondering if my fan clutch is running too much all the time. I am over cooling and temps swing between 190 and 175. Cycles more less. How do you diagnose if the clutch is working properly?

I did some more measuring and testing for the MPG crowd. Before I start I will say that I just verified my SGII and its right close to being on the money (off by 0.2 gallons). I'll assume that a slight error between the ScanGauge and the fuel pump. Now I my truck conditions are Edge set for 5x3, IAT fooled to 143*F, Engine coolant varied from 188*F to 197*F, winter fronts still on. Actual weather was high of 65*F (actual IAT was ~90-105*F) Now since I was on I-84 down in southern Idaho today I figure I open the beast up and let it fly low for once. So I set the cruise for 75 MPH and reset the current MPG counter and measure for about 20 miles of highway. I was p…

Fuel pressure is up around 20 at idle, drops to 15-16 when I get on it. No codes though. I did have a 0216 code from when my lift pump went out over a year ago but it cleared and has never came back. No codes at all? It stopped doing it for awhile but started doing it again. After I shut it off and start it again (sometimes more than once) its fine. Any suggestions on where to start without codes. Ive searched the forum , alot of dead pedal issues but they have codes.

does any one have the Bully Dog WatchDog . how do you like it is it worth the money.

Have joined and trying to download the 99 fsm. Any hints on why it will not let me download as after logging in says not allowed. thanks

so I got a airdog 150 off a cracked block engine. My question is do I need to put a draw straw in my tank or can I use the stock suction line? also the bed will be off the truck as I"m repainting the frame so migth be a good time for tank upgrades? just not sure if the draw straw is the way to go. Thanks

Has anyone used this tool....? They have it on sale for 99.99 and it has a bunch of good reviews.

There aren't many guys doing it. Only one guy on the net I can find so far and he had troubles. Ended up just goin back to the PCM voltage regulator. :think:I want to do it because of RFI noises and possible damage to the computer. This is according to a couple electrical engineers recommendations I was reading about .

to start this off ill give yall a little back ground info on the truck its a 2001 5 speed with 124,000 miles has the usual mods dual disk airdog 150 new injection pump as of 25,000 ago afe intake 5 inch exhaust the truck has had a no start issue in the past but sort of comes and goes intermittently. The symptoms include, when you turn the key on the is a 3 second or more delay until the liftpump comes on, the wait to start light only comes on for about 2 seconds and the truck will not start Also with the key in the run position you cannout hear or feel the asd relay click, ive checked the relay and confrimed that it is working..the …

Alright guys, I am new to this forum and did a lot of reading on the TC lock/unlock thread and was hoping my alternater could be causing my TC to have problems. I took some voltage readings and based on what I was reading in the other thead I throught I might have a problem: [TABLE=width: 504][TR][TD]Battery Volts AC [/TD][TD] [/TD][TD][/TD][TD]0.039 - 0.041[/TD][TD]FAIL[/TD][/TR][/TABLE]Based on these I thought my alternater was going bad, but I took the truck to a shop today and he tested it on the truck and said voltage was good and the diodes were good. So on my way home I stopped at the local shop and talked with the owner about my problem and we went for a test d…

My 2001 is pinging like an old gas motor that has cheap fuel. Is this a bad injector or something else?

Well I gone and added the 4th switch to my setup. It didn't take long at all to daisy chain in the 3rd switch to the IAT and make it functional. No longer have to play with rheostat's or stuffing the IAT plug with wires. I'll get my video up here really quick.

My truck came with an S&B intake installed and a straight pipe. I threw a muffler on the straight pipe in a quest to make highway travel more civilized. Now I can hear the low drone of the intake. I don't mind it around town, but on highway trips it becomes noticeable. So the question is how much louder is the intake vs the stock air box? Would it be worth it to throw the stocker back on? Will it cost anything performance wise?

Hello all, I recently replaced my stock turbo because i noticed it was leaking some oil by and it had some end play. It just so happens I came into a sweet deal on a slightly used BD super B. This turbo is for a 2003 cummins but the only difference I could find for install was changing the exhaust downpipe. So the problem is now I'm down about 2-3 mpg. There is a noticable power gain and broader torque curve but peak power seems to be at about the same RPM as it was before. I am not having much luck finding specs. for this turbo but everything I've read says its not much bigger than stock other than the exhaust housing is quite a bit larger. Any input would be appreciate…

Engine light came on. When I chkd code by turning key 3x, I got P0237. How do I clear the code so that after I disconnect the Quad module, I can see if that was the problem? If not the Quad, I assume its the MAP sensor. Anything else I should consider? By the way, where's the MAP sensor located?thx,Eric
