Question about 1996 Jeep Grand Cherokee

1 Answer

Starts but won't stay running

My 96 Jeep Cherokee kicks over but unless i keep my foot on the gas it stalls. If i keep the revs over 1500 and slowly take my foot off the accelorator and drop it to 750 revs it kicks in ok, if it goes below 750 i have to keep the idle about 1000 revs,it's like i am resetting the computer. I know it's a fuel problem of some sort though i dont have the money right now to get it diagnosed. I am hopping someone out there has had the same problem and can give me some advise.Thanks

I would sooner think it was caarbon on the throttle plates and a very dirty idle air control
Take off the air intake tubing so you can see the throttle plate on the rear side of the throttlebody there is a small round electrical item the connector will likely come in from the side on the end of this item it will have two (2) TORX head screws holding it on you can see the tim if you get a bright flashlight and look straight down into the hole in the throttlebody near the idle air controller you hould see a tapered plunger its likely all coated with carbon. its best to remove the IAC and thuroughly clean it but some good carb spray may do it on the plunger. Now open the throttle and put a stick or a brick on the accelerator pedal of course with the engine off!!!!! the throttle plate will wide open dont put your fingers in theere in case the accelerator snaps shut it will cut your finger nearly off, clean BOTH sides of the place till its spotless and the walls as far down as you can reach all around rinse it good with carb cleaner and take the block off the accelerator , put everything back togother and start it it will start hard but it will start and rev it up gently a few times and see if it idles better if not you need to remove the IAC and clean correctly.If this information helps please give me a fixya Rating thanks,Randy
contact me if you have any questions
you should use about half the can of carb cleaner to do this.

1999 Cherokee starts but won't keep running without giving it throttle.


Assuming everything is working correctly, you may have to drive it up to 50 miles for the computer to relearn the basic perimeters.
I think you can also turn the key on, open the throttle to wide open, then close it 2 or 3 times to reset the memory in the computer.
Not sure about Jeeps.

My 1998 dodge caravan won't stay running. starts up but shuts down instantantly or when i take my foot off the gas pedal,


ok i have a 1998 durango with the 5.2L 318 engine. had trouble with a bad cell in my battery. I went out bought an optima red top battery for it 800cca. put it in and had same trouble. No start without putting foot on gas. wouldn't stay running without holding foot on gas. CPU has to relearn it's programming once you unplug it for long periods of time. mine was without power for about 2-3 weeks till i got new battery. Start with this.. first check under air filter make sure a squirrel hasn't made a mess under your air filter and it's clogging the air intake. Then pull off the lid to your injector cover ( the screw down lid coming from the air box ( with air filter in it) to "carb") make sure all your cables move freely. put that all back together and close hood. Start truck with foot slightly on gas pedal to get started. keep it at about 1k to 1500 rpm for about 1-2 minutes. Rev motor to about 2500rpm and let it die out if it will. Get out lock doors with key fob if you have it. if not make sure to lock doors. ( trust me it worked for me) let sit for 5 minutes. come back out and unlock door and relock door 3 times with fob ( if you have it ) or key if you don't have a fob. Then unlock it with the key and enter vehicle. Start truck as before and keep it around 1k to 1500 rpm again for about 30 seconds rev it up and should keep running. Mine did. I think the iac was stuck from sitting and has now since loosened up.
Good luck hope ti works for you.

Jeep 2002 grand cherokee dies unless i keep foot on the gas...


The idle relearn needs reset. Keep your foot on the gas at about 900 rpm. Make it idle for about 5-6 minutes. Slowly ease up on the gas until it will idle on it's own, it might take a while. After you get it to idle, it might be idling real low, but on its own, Let it sit and idle until for 20 minutes. After that it should be back to normal. You will have to do this every time you have the battery unhooked for a while.

Car won't run without foot on accelerator.


its very important that the throttle body especially around the throttle blade be spotless clean or they will stall every now and then. then progress to refuse to idle at all. take off the rubber air intake pipe from the top of throttle body [has 3 torqes screws] open throtle by hand and look for carbon/grease/soot etc were the throttle sits when closed. clean with toothbrush and some caeb cleaner get all black off and dont forget the blade, both sides and the edges. scrub then rinse with carb cleaner untill shiny.spray some cleaner in the hole that is on top off the body to. that is your idle air controll motor port.put back together.it will be hard to start at first so hold gas pedal half way down untill it starts then slowly [real slow] let foot off untill you are no longer pressing it. put in reverse and let it idle there a few seconds then do the same in drive. that should do it. sometimes it may stall a couple of times when driving dont hold foot on gas just let it die then restart this allows the computer to readjust its idle stratagee

I had the same problem with my 96 Dodge Ram, it would crank up but if you let off the gas it would die. It needs a map sensor!!

STARTS BUT WILL NOT STAY RUNNING


Check the throttle position sensor"tps",or the idle air control "iac" by chance did the battery go dead or was unhooked?
if so the ecu was reset and needs to relearn idle settings by just keeping it running for a few minutes

Where is the gas leaking from? To clear a flooded engine, keep your foot all the way down on the gas pedal while you try to start the car. As it starts keep holding until it sounds like it's smothing out then slowly release. You can also change the spark plugs if that does not work.
