my 2007 was stuttering when stopping. i disconnected the battery removed the MAF sensor cleaned it and replaced it. the car drove fine for a couple of days. then the problem return. I repeated the process. again it ran fine for a couple of the days, then the problem returned. I bought a new MAF sensor. It ran fine for three days then the problem returned. I took it to Advance auto parts. because the check engine light was on. they said it gave the code P2637 torque management feedback signal "A". I thought it was the MAF sensor from reading post on this website.
Any help would be greatly appreciated .

Also every time I disconnect the battery cable and reconnect it. It runs fine for a day or so.

Is your car an automatic? If so, check the cam s
Position sensers and cam servos.

Yes it is an automatic. Also when I disconnect the battery then reconnect it runs fine for a day or so

That is classic behavior for ECM to TCM communication issues resulting from under performing or failed cam sensors or servos

Go toward the end of this thread and see how issues were identified and in the main resolved

So should I take it to the shop and let them figure out which cam sensor is bad. I would really hate to take it in. I always feel I'm getting ripped off. Or should I just replace all the sensors till this stop.

Only you can make that decision.

If you read the how to threads on swapping out the servos and sensers, it appears to be a very easy job. The dealers in the past have not been very good at finding failing but not failed units and sent owners back on the road with " unable to reproduce"

As an option, you could ask them to identify which part is bad. If they know what they are looking for the difficulty should be reduced.

Worst case is you buy replacements one at a time and swap them yourself until the problem goes away.
