2002 IAC valve replacement / relearn procedure Lincoln LS
- Thread starter jellyfish
- Start date
I remember seeing something posted about it years ago, but it was something insane with like 30 steps accelerating and stopping.Hi,
I replaced the idle air control valve on my Lincoln LS and it's acting weird. Does anyone know the relearn procedure?
Thank you
Fwiw, I replaced mine (turned out my positive wiring was bad so ran a new wire) and did no “relearning”. Ran fine right away.
Chances are you have another issue. What made you think it’s the IACV?
I never replaced the IACV on my 06 LS but on some of my other vehicles i just replaced it and drove it normally. Never had a problem. Also not every new part is a good part. Some can be faulty. You can check the IACV by taking a screwdriver and pushing on the spring to see if it opens and closes. It should have some tension but If it doesn't open and close then its bad. Did you use a gasket? What made you think the IACV was bad?Hi,

Glad you got it sorted out and thanks for letting us know what the solution was to you're problem.It was a 'bad' new idle air control valve. The LS wanted motorcraft brand I guess.
Now we are going to try to change the degas bottle : )Glad you got it sorted out and thanks for letting us know what the solution was to you're problem.
It was the IAC V and it was driving ok, it was just making this weird breathy noise and if you tapped on the IAC V it would stop it. It's good now. I had to use a Motorcraft IAC. The other brand was very bad and made the car drive wacky.I remember seeing something posted about it years ago, but it was something insane with like 30 steps accelerating and stopping.

Once you get to it ,its not that hard to change. When i first bought my LS i took my degas bottle out and inspected it after reading all the threads on here about them cracking over time. Mine looked great so i put it right back in.Now we are going to try to change the degas bottle : )
