Read Battery Change = Bad Idle

Guys,

Just took out my battery in the EB today to put into my XF Van just to start the thing and move it, then put the battery back into EB and it doesnt know if it wants to idle or stall when you start it.

I just cleaned the ISC and that took care of the idle problem when I put the A/C on.

Does the ECU have EEPROMs?...Do they have to relearn how the car was setup after you remove a battery?..I wouldnt have thought so.

Does anyone have ideas?...The car ran fine before this. Have checked terminals and connections, all ok.

Car runs fine above idle and when stopped at lights.

it will come good, they take a few k's before they re-learn.

Serious.
They need more than 10k's, 100 or so k's will do it.

Does this happen to everyone when they get their car serviced for a battery??..Surely not..Id be pissed if it came back from the workshop after they had disconnected my batttery and it came back that way..

Guess I will have to wait and see if this that you say is true.

I still remain dubious..hehe

I think it has a very short-term memory, like 10mins or something.

If it's a quick out & in replacement job things are usually fine, otherwies it's as you describe. It'll get better pretty soon.

I think there is a procedure to run through (different idle speeds for so many mins, aircon on/off etc) that resets things so that you wouldn't really notice. Otherwise you'll just have to put up with it until it has relearnt by itself.

I inherited a VX commode as a work vehicle and had the opposite happen. It was extremely slow and went like a dog. The battery failed and they put a new one in and it was like it had another two cylinders. Previously it was driven by an old bloke who didnt accelerate fast. Still has a horrible transmission and the seat gives me a sore back tho
Regds,

According to the manuel I have. You have 10min to swap batteries.

As said, just give it time to relearn.

if you don't want to drive it to relearn the proper procedure is to let it idle in neutral for 10mins, then idles in neutral with ac on for 10mins then idle in drive for 10mins and finally idle in drive with ac on for 10mins. then all will be good. this is what is done if a car plays up after a battery change in the dealerships. This isn't a problem in cars after EBII from memory
