This sounds like part two of your other question....make sure throttle return spring is in place and that the throttle cable is free to move and not holding the throttle open. If you had the intake manifold removed, make sure it isn't leaking. If the idle was fine before you did whatever repair you made, most likely you have something put together wrong or left a hose off somewhere..

Trial and error won't reset the basic timing, merely cause more frustration and delay and could damage the oxygen sensor and CAT in addition.

An engine with too much unburned fuel inside is likely to give up all efforts at starting and once you have set the timing you might need to do considerable cranking with the throttle wide open and the fuel pump disconnected before it does start.

An experienced mechanic could probably figure out the timing close enough to run reasonably but for accuracy the repair manual will provide the proper procedure.

My 99 buick regal cranks over and starts but has trouble running. If you give it gas to help it through the start up it levels out and runs fine. Fuel pump is good, I've changed spark plugs and wires,


sounds like a stuck open EGR valve to me , take it off of a cool engine and spray some carb cleaner around the seat see if any leaks through to the other side. If it does The valve is bad. Also check out your throttle body for carbon and gumming. W/ engine off spray an appropriate carburator
cleaner into the opening and clean throttle plate and bore with a rag until shiney. put all the air cleaner hoses back together and hold throttle to floor momentarily until engine starts, then rev up half way and release throttle twice quickly, now allow engine to idle idle should be stable and smooth. If not then check for other sources of vaccume leaks.

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.

After i changed the battery in my 98 new beetle the idle wasnt correct and i had driven it so the ecu can relearn the idle and it still hasnt relearned it i had let it set over night and the next morning...


To get it to run you should be able to just turn the key to on, without starting the engine, then put the gas pedal to the floor and hold it there for 5 seconds. This lets the computer know where full throttle is. To really fix it you should clean the throttle body. You can do this just by taking off the plastic boot that goes to the first metal piece of the engine, and working around the throttle plate with a rag and some carburetor cleaner. Make sure to clean the top and bottom of the cylinder that the throttle plate seals to, You can see the throttle cable right there, move the throttle plate to wide open manually so you can fully clean the bore.

The only way an engine can run Wide open is if the throttle plate is opened all the way, allowing a large volume of air in to the engine. Check the throttle plate and see if it is hung up or possibly the throttle cable is frayed and holding the throttle open. It is not the injectors, they operate on inputs from the PCM.

Engin stops sometimes when I slow down, usely starts back up and run fine. Now I am at home it starts then stops, now it turns over but will not start and run.


it has a dirty throttle body. get some carb cleaner and a tooth brush.remove air cleaner hose at the throttle body. block open throttle to wide open {engine off of course} or have someone hold it to the floor.spray cleaner into body and scub with tooth brush especially were the throttle plat touches the bore when at idle and the throttle plate itself.spray brush,spray,brush. put hose back on and start engine. you might have to give it some gas to atart it then its going to run rough for a few seconds but it will clear up.slowly lower foot from gas pedal and allow to idle.put in reverse let run in reverse for a few seconda do the same with drive.it has now began to learn what position the stepper motor should be in when throttle is not depressed.it may stumble a couple of times at sops but will soon correct itself

have you attempted to clean throttle plate? I would suggest taking hose off of throttle plate.Hold it wide open and spray throttle body cleaner, (with it not running) let it dry if it is really black or gooey spray and wipe goo and fluid off with a rag.put back together.It may not be problem but if air filter was dirty throttle plate most likely is.
