Creating a vacuum leak helps to lean the mixture out and makes it run better. http://www.ihonlynorth.com/forums/carb-tech/511-holley-22xx-series-carb-stuff.html, (You must log in or sign up to reply here. After I drive for a while, from 3 to 5 minutes, it will idle again. In which case, the heads need to come off and get reworked. I don't think there is any learning with the idle, the PCM simply drives the IAS to try to hold an idle rpm that it thinks is best. It is normal on dodge for them not to idle after a dead battery. I'm coming up with nothing else though. I'll listen in to see what I can hear. Ken. problem. Come join the discussion about performance, modifications, classifieds, troubleshooting, maintenance, and more! Ignition timing is set according to the firing of the number one spark plug, that is the plug that fires first in the ignition firing order. Low voltage will definitely affect AIS operation. Sometimes bumping the RPMs up a little with the accelerator pedal helped. Both components cost me $60 total from Advance Auto Parts. It has about 130,000 miles on it and once in a while when you take off from an idle the engine will stumble when you step on the gas and it wouldn't stop unitl you let off the gas and step on it … I have been replacing things lately with not a lot of luck. Privacy Policy. How many miles on this engine? Couple of questions. The 2003 Dodge Ram 1500 has 28 problems reported for engine stalls out at stops or low idle randomly. "the hearing, that is". If all checks out look for voltage leaks/shorts. The 360, 5.9 does not idle rough, auto trans shifts smoothly, no leaks, or rattles, fit and finish is tight. Make sure you place your air cleaner lid back on before cranking the motor in case of backfire. Average repair cost is $440 at 100,650 miles. Engine ran great in the summer....runs like shit in the cold weather. So, the stalling after starting is normal, but its NOT because of the PCM learning idle again, its because the corrections factors for A/F ratio is all off. By retracting, it opens up the air passage around the throttle blade. A man I do work for has a 99 Dodge Ram 2500 360/auto.4X4.Over the winter the battery went completely dead. Jay He has to keep his foot on the gas until it warms up or it'll cut out. JavaScript is disabled. Using solvent and a toothbrush, clean the area between the throttle bores and blades. Air pressure coming out the oil-breather/filler tube/dipstick hole? I have replace Throttle position sensor and Idle Air control, replace wires. Remove IAC motor/valve on side of throttle body that regulates idle especially under load conditions, and clean it & the port good with throttle body cleaner & re-try. There's two plans of attack. If not, maybe the valves are so loose in the guides, that the valves just aren't sealing well. Those corrections factors are stored in a table in the volatile memory of the PCM (meaning it all disappears when the PCM loses power long enough that the capacitors in it drain down). Need some help on my old dodge 360 motor. While you have your torx screwdriver out, change or at least clean the Idle Air Control also, mine was all gunked up. Terms of Service. The Dodge 360 cubic inch displacement V8 engine was introduced in 1970, and has been used in many car and light truck applications. I have to give it some gas to keep it running. This truck was manufctd in Mexico! If so, it sounds like a timing problem. Running too little initial timing with a performance cam will cause backfiring, poor idling, stalling, and sluggish performance off idle along with hesitations, etc. The intake will likely need replacement but not necessarily. How good was the rebuild?? RE: cold idle/stalling IP: Logged Message: I have a 1996 dodge Dakota 3.9 engine, truck is stalling when cold. tried to start it one morning and it was acting like the battery was going dead. The stock one was only showing to the first bar. Machineguns took most of that from me though. The ports in your intake between the carburetor and the leak you plugged are for the EGR valve that was held down on the 2 studs. That, along with an increased injector pulse width, raises engine speed to produce the idle flare-up to 1500 rpm when you start the engine. More likely the plenum gasket is leaking. If the memory gets reset, it will stall at idle for awhile. Take truck to local auto parts store and get battery and alternator checked for free. I ran outta gas the other day in my driveway no less. You can spray carb cleaner around the base of the carb with it idling and see if it raises the idle at all. Or the throttle body is carboned up. The upper adjustment screw is the idle mixture screw, while the lower one is your idle speed adjustment. You're signed out. So a "reset" PCM (meaning it lost all electrical power long enough to dump its volatile memory) will have start its learning from scratch. The "learning" you're talking about is the PCM storing correction factors for A/F ratios that it learns from the corrections it has to make from reading the O2 sensor and adjusting A/F ratio. do you have a known good carb to try out? Tap to unmute. I would run it with drygas in it, take a long highway drive and fill it up with fresh gas. The fact the the battery was very low may indicate a problem. The highway driving speed averages 75-80 mph @5hr intervals and the comfort factor is remarkable. Any history on it?? 1989 Dodge D150 318ci TBI 2wd 1/2 ton Automatic Symptoms: Idle raises and lowers, after warming up. How did you intentionally introduce vac leak? Look down the neck of the radiator when it's running, and look for bubbles in the coolant. I put gas in it and it started right up, doesn't run rough or anything but when you let off the gas it dies. I put an aftermarket one on, and its running about 45 to 50 going down the road. I'm tellin ya...plugged exhaust cross over in the intake....seen it many, many times and repaired it many many times... would you also suggest physically checking the chain? What should the oil pressure read? It took a while for us to find the reason for this problem when I worked for our local city shop..[we had dozens of dodge pickups] .it was the same thing everytime. TPS has nothing to do with your idle. It doesn't cough or … Discussion in 'The Hokey Ass Message Board' started by NintendoKD, Jan 15, 2012. Don't want you doing that though before you've eliminated other causes. I have done all of the standard tuning, I will list it. Any heavy blow-by? The choke stays closed too long making the mixture stay too rich for too long. I've run into this problem time and time again with SB mopars with carburetors. Then the second time it would catch and idle rough for a few seconds then all was good. Once system voltage gets back to normal it should idle again. I like this! The number one spark plug is … I would suggest taking a fuel pressure check to see what the output is. Thursday, Feb 22, 2007, 05:46 PM. I have a 1976 Winnebago Minnie Winnie on a Dodge chassis (b300 I believe) with a 360 motor. Yes got it to run,idle rough drove it cleaned out the AIS. If playback doesn't begin shortly, try restarting your device. I've had them crack and create a vacuum leak. Thank you n advance. From my experience they wont idle after a power down situation. If there is no vacuum leak it shouldn't affect anything at all. How much cranking of the idle speed adjustment take? was rebuilt. I actually have to let it run for 15-20 minutes for it not to stall. Take the air cleaner off of the top of the Dodge carburetor by removing the wing nut on the air cleaner by hand and setting it aside. My 95 dodge ram 360 wont idle while driving but will in park.?
