Strange AMM Problem? 200

85 - 240 - 205,000

My car suddenly developed a problem where it will run choppy - like a 'missing' problem - when the car is cold. Usually, it will run fine once the car has been driven for 10 to 20 minutes. Sometimes, it runs fine when cold, but when I go over a large bump the problem starts (this doesn't happen often).

I've had AMM problems in the past (and had it replaced two years ago - new), but back then the car wouldn't idle at all and would just die all the time.

It seems to me that I had read here several years back that there could be a problem with AMMs sticking; not adjusting when it is supposed to. Perhaps my memory is incorrect. Not finding it in the archives now, though.

If anyone has an info on this - or what this problem could be - it would be greatly appreciated.

Thanks in advance.
