#12 of 267 Idle surge
Jul 02, 2007 (8:24 am)
I have a 2002 Quadcab with 4.7 engine and about 106K miles. Lately, when I start the engine it surges, (i.e. revs to about 1500 RPM then idles back to about 700 RPM). It will fluctuate back and forth for a bit before idle finally smooths out. Is this a sensor problem? Or a dirty throttle body?
I was finally able to get a Haynes manual. In the tune-up section, it states in several places not to clean throttle body with carburator cleaner.
I'd appreciate any suggestions.

Idle Air Controller was dirty. I removed it and cleaned it good.
#14 of 267 multiple problems
Jul 07, 2007 (12:08 pm)
i have a 1996 dodge Ram with the 5.9 and it will fluctuate between like 450 RPMs and 700 RPMs and when im in reverse if i dont keep my foot on the gas every once in a while it dies. Im not sure how to fix it. another problem is when im sitting at an idle it feels like its missing horribly, and i changed the plugs wires cap and rotor but the truck has 187000 miles on it so i dont know if its the timing chain is stretched and thats causing it or what it is so if you have any ideas let me know. thanx

I don't believe a stretched timing chain could cause this problem.
My first suggestion would be to thoroughly clean the throttlebody, check for a clogged PCV valve, and also check for brittle and cracked vacuum hoses.

#18 of 267 2000 Ram 1500 318 multiple misfires
Aug 08, 2007 (3:38 am)
I have a 2000 Ram 1500 318 automatic. Will loose power and misfire really bad. Hooked up to hand scanner pending codes were multiple misfires on cylinder 1 and 3 and lean on bank one. Towed to shop and ran fine when got there. This has happened about four times. No vacumm leak at intake. All new plugs, wires, cap and button. ECM okay. Good fuel rail pressure. Dropped tank and check fuel filter and pump.
#19 of 267 02 RAM 1500 Sport Quad Cab 5.9L - 1 minute misfire
Aug 08, 2007 (11:03 am)
The engine starts ok, but after about 2 minutes it misfires/no power for about 1 minute (occasionally stalls), then it settles down and runs ok. This happens with the engine either hot or cold, after every start unless it is off for only a few minutes. The scanner says it misfired on cylinders 4 and 8. Any advice appreciated - I was told to replace plugs/cables etc. but I'm not so sure. Thanks.
ps. about a month ago, it would start real rough after a rain, but this seems to have disappeared? - not sure if this is related to the above problem.
#20 of 267 Re: 1999 Ram 3500 Cummins Engine dies while driving [hodgepodge1]

Between 98 and 02 the cummins lift pump located in the side of the block was a horrible design. They changed it from a mechanical pump that was run off the cam shaft to an electric pump mounted roughly in the same location (the drivers side of the block, behind the injection pump.) You can go to the dealer and get a retrofit kit that moves the pump into the tank. You can also get it from Cummins for a little less money. It's somewhat time consuming and there is an electrical harness that must be installed with the kit.
#21 of 267 Dodge Ram 1500 rpms jumping up and down?
Sep 09, 2007 (1:35 pm)
I have a 2003 Dodge Ram 1500 (4.7) v-8 quad cab. The rpms idle erractically especiallly at stop lights. While driving, the truck is okay. At slow drives (2-10 M.P.H.) the truck may cut off. I been dealing with this problem for about 2 months before I finally decided to raise the hood as well as my sleeves. Now what I did was 1.Disconnect air filter and check the condition. 2. Disconnect Air Resonator box on top and remove( make sure to disconnect air charge sensor wire and hose on the other side) 3.Inside the AIR RESONATOR BOX is an air charge sensor(blue color tip)check it for dust, apply light pressure and clean it with a clean rag. 4. Get a can of injection cleaner and lightly spray inside of throttle body around the plate/below the throttle body is a smile-like opening, get a flat head screwdriver and wrap it with a clean cloth and stick it in there and wipe inside of that compartment. 5. Start engine and slightly idle up 30 seconds). 6. Turn engine off and reconnect every thing back (Don't forget to reconnect air charge wire and hose). 7. The check engine light may come on , but don't be alarmed. That's just your air charge sensor adjusting. It will go out soon. Voila! this worked for me and hopefully for you also. Now my Ram is steady idled at about 600 rpms at stop lights,and it doesn't stall anymore. To make a long story short, just clean your throttle body and check your air charge sensor to start with. Good Luck.
