This has happend about 4 times now after a long drive if I am just cruising in town @ very low RPM below 2K I feel a stutter that comes and goes. Check Engine light will come on but it will go away a days or 2 later. My most recent event was last night and it happend on the freeway but I was also cruising below 2K hardly pressing on the gas. If I keep rev's up 2K or a little above stutter goes away quickly. @ idle car idles fine. Car has 83K on it. when this happend last I was on 96 octane gas.

What could this be?

Sounds like a misfire, when was the last time the plugs were changed?
Check your air filters as well

stazang

Air filter is fine I have a set of K&N that I keep clean all the time. I have never changed the plugs and yes I want to do so but the freakin hole for the plugs is really small and I need to figure out what kind of tools I need to change them out. I have also never change the fuel filter so I am suspecting that as well.

Wouldn't a miss fire happen @ all RPM's?

Hulk

It wouldn't ness. Happen at all rpms, when it happens again go read the code, at autozone or something, that will definately tell you what it is, as of right now it's all a guessing game, could also be clogged cats, see how many things it could be? Lol

I think your KN filters is causing the MAF to go bad.

at that mileage you may need your intake gaskets replaced. I had about 62k and would get a CEL after a hard pull or drag racing, read P2187 with a generic scanner. If that's the code you get (i had it checked for free at pepboys) I'd check that out.

pleanty of other thready explaining this, but basically the intake wasn't torqued right from the factory and after time/use the gaskets sometimes developed a leak

stazang

Already redid the intake gasket but I will retorque them and see. This only happens @ really low RPM car runs smooth and fine @ all other RPM's. Also even @ Low RPM it does not happen often.

Why would a filter cause the MAF to go bad?

moosejaw

The oil from the filter clogs it up
so you need to clean your MAF

stazang

Whats the best way to clean the MAF? should I use some sort of break cleaner or oil based cleaner. From what I remember they looked clean but I will take a closer look.

Peter_02AMG

There no guarantee cleaning it will work. You need the spray stuff they use to clean electronic components from Radio shack. You got two MAF and they are expensive to replace. There is a way to check if your MAF is bad. Just unplug its and take a test drive around to see if it better. Yes it ok to drive with it unplug. GL

Unplugging will not tell me anything. as I said this very rarely happens and only @ very low RPM but I can not reporoduce this problem that easily it happens rarely.
