01 Dodge Ram Help

[elemonator]

My son just bought an 01 Dodge Ram 1500,4x4,5.9 magnum 117000mi,sat for a while,less than a year,we drove it,bought it and drove @10 miles,drove fine shifted fine, After about half tank of gas we took off toward home,it ran great then within 2-3 miles of the gas station,its sputtering in low rpm,when its in O/D,turn off O/D runs great,when low rpm in drive it wants to die,starts right back up,I was thinking air filter,but if thats not it,water in gas? He put some STP gas treatment. any legit help it appreciated....ie,no Junk Dodge remarks...lol

II once bought a car that "sat" for a while. The fuel filter was plugged with varnished gas. I'd look at the fuel filter first or at least check for full pressure at the injectors.

This, same thing happened to me....

It's a dodge, what do you expect? Atleast it didn't catch fire.
Sorry, had to!

Check the fuel filter for tiny little specks of rust/debris. Had to replace a fuel fiter, carb and fuel pump on an older vehicle that sat for a while. Hope you have fewer issues with this one!!

Sounds like bad gas. FYI there is no serviceable fuel filter on that truck. The filter is built into the pump, you have to drop the tank to change it.

I know dodge fuel filters are inside the tank,we have a Durango...his air filter was full of nut shells,I guess from a chipmunk and the tube to the fender was full too,cleaned it out,but it is still doing it,He's bringing it over after he gets off work,I'm going to pull a couple plugs look them over,his cap and rotor,see if its wet,try resetting the computer(IDK if that will change anything),I told him drive it w/ th OD off burn up that old gas.

If it's an 01, does it have a cap and rotor?

That is prime year range for the crap transmissions as well. Since it's only doing od things with the trans in a certain gear, I would think the two may be related. Have you scanned for codes yet? On a newer vehicle that should be diagnostic step #1.

 

[elemonator]

We did the codes first,but usually if a vehicle is already running bad,it'll pop all kinds of codes,it had like 8 codes,from cyl misfire to o2 sensors,to timing chain,it came out of the running bad at low rpms now it won't idle,ordered an IAC sensor,we'll be putting on a tune up this weekend,cap,rotor plugs and wires,as far as tranny goes,thanks for the heads up..I'll be sure to let him know we should probably do a filter/fluid change in the transmission also.Are the trannys known for any particular problem,or just catastrophic failure?? ....he'll love that...

I thought they fixed the transmission problems after 96?

It's the coil pack . Had one do the same thing but mine did after a rain. It's a cheap fix just two bolts and easy to get to.. Just make sude you clean the mounting area up real good so it gets a good ground... Mine was a 2001 1500 4x4 and the moister made it run just like you are saying... During nice weather it would run just fine... Hope this helps, if all else fails...?

The truck will not idle,the chugging while driving stopped,now whenever you let off the gas it wants to die,changed the IAC sensor and air filter,no change,only does it when its warm,runs great other than at idle....think that could be the coil? Runs sporadic just before it dies,like you can almost predict the moment its going to die he doesnt have the money to throw parts at it so the help is welcomed!

Might be a vacuum leak at the intake. Use the propane and rubber hose trick and see is the idle smooths out.

Throttle position sensor?

 

[Fargo]

Sounds a lot like the egr valve is stuck.

 

[BGDave]

Advance Auto Parts: Search Results for air idle valve

This stinking thing is a prime suspect.

After install be sure to disconect the battery for a few minutes. This was not included in the directions for mine, but is necessary.

Good luck.

This and possibly the coil pack.
I gave up on the Mopars a while back. I got tired of putting all the time and money in on them.
Those trannys were notorious for sticking solenoids and ecm issues that had to be reprogrammed by the dealer or shop with specialized gear.

My 03 is doing the same thing. I pulled the new IAS cleaned it up and it ran fine for a week, then right back to it.
If I figure it out I'll post here, please do the same.

Took it to a garage and it was diagnosed as a crank position sensor,we'll see.....
