After you change the battery in a 2004 jeep grand cherekee do you have to do anything to reprogram it?


Ok, I can answer this one!! The problem when disconnecting the battery the computers reset to the factory initial settings.. This feature is greet when you need to reset the Check engine light, but raises cane when you restart the vehicle.

All of the drive parameters are reset along with the PCM and body electronics module.

The idle many times is lost and the car will not idle. Be sure when you restart not to depress the gas pedal or it will take several minutes before it will relearn idle and will likely stall in the process.

Also the computers can upset when you reconnect the battery. It is possible that you may have to reset a second time if things are a little crazy after reconnecting the battery. The connection will arc and can cause the computers to have a faulty reboot. Wait several minutes before trying a second time.

It will take several miles of driving for the PCM (computer) to map the air fuel so it may miss behave during this learning cycle.. After a few trips all we be well.

There is a process that some shops use to maintain power when swaping out a battery.

1988 Mercedes Benz 300E 3.0L Gasoline F.I. ''Sputtering at Idle


ok..you must have more than one car???? you don't drive the 300 atall im guessing. #1 start car drive up the road and \back to your house. #2 let it idle till problem starts. #3 once it does start with the problem keep it alive with the gas pedal. #4 once your have it safely from dying in higher rpms "rev it" like a kid would, you know like if you were gonna race some one lol. be careful not to over rev or damage engine. you should do this for five minutes no longer than that. #5 let it idle for another 5 minutes. #6 repeat every day until problem with idling decipates. it took mine 3 300e like 3 days of this. if your not going to drive the car once you get the problem out of the way. turn the car on everyday and let it idle for 5 minutes atleast and take it for a short drive once a week. they get lonelly you know lol. later on you can just turn the car on every 2 -3 days and let it idle but still take it on a short drive atleast once a week

TH Magna stalling in idle after battery replacement


Hi - what was the solution??

Ive just had exactly this problem. Got new battery today then no idle. The car starts fine and runs for abourt 1 second then instantly dies. Its fine if you keep your foot on the throttle. Unfortunately if you are going downhill as soon as you place your foot on the brake the engine dies and the steering fails - then the brakes!!!

I seem to remember having idle problems the last time I replaced the battery. but not as severe.

Any how I got home after nearly crashing with starting the engine 20 times. Then with the engine off I pressed the throttle right to the floor and released.- and then restarted. That seemed to work for some reason ??? The Idle is now 100% ok although still a bit rough. But at least does't stall.
I cant see why doing anything to the throttle pedal/cable should affect the idle to be killed.?? even if the cable snapped it should still idle.
NB about 10% of the starts the idle actually idled ok for a few minutes before failing again

Any thoughts greatfully received

I now darent go out!!

1993 Ford Escort 1.9L Auto Randomly Stalls


I don't have the solution, but I have the same exact problem on my 1991 Escort 1.9L with auto with 120K miles. I replaced the IAC with no difference. In fact I unplugged it, and still had the random stalling. Also disconnected the EGR vacuum line...still stalled randomly. After it stalls it always starts right back up again. Sometimes it will act as if it's going to stall, but comes back to normal idle. Park or Drive makes no difference. Acceleration and all normal driving is fine. The next thing I was going to try is hooking up a timing light and watch to see if the timing light stops flashing as it's stalling, and/or hooking up a fuel pressure gauge somehow, to the fuel rail, to see if the pressure drops when stalling....to figure out if its ignition or fuel related.

Stalls just after idling for more than 3 minutes


I had the same problem. you have to either keep replacing the filter until the line has cleaned out or blow the filter out with an air hose. Tedious but cheap.

2002 sequioa sudden stall


Often when the battery is disconnected or replaced the computer will lose it's learned idle settings. You could try letting the engine idle in park until the engine temperature comes up to normal and leave it like that for a few minutes, then put the Air con on and let it idle again for a few minutes, then switch the air con off and put it into drive. If it does not stall, let it idle in drive for 2 minutes or so, and then do the same with the Air con on. This should relearn the base idle settings and stop it from stalling on you. Before you carry out this procedure you should make sure that when you replaced the battery you didn't remove any other plugs or knocked anything that may be causing the fault. If you try this procedure and it still stall when you select drive, you will need to get a Mechanic to check the vehicle over.

Hope this helps,
Mark.
