Driving FaSSt

Okay so my car still has a hesitation right around 3,000 rpms

Things I have done to try and get rid of it are: New Plugs, Wires, fuel filter, seafoam through brake booster, seafoam in gas tank, cleaned maf, and checked the air filter.

So after work tonight I got the mechanics scanner and scanned it. Its a Snap-On Modis same one my High School has anyway the codes its setting off are P0137 and P0157 both are something about the 02's

Any Help will be much appreciated and needed

PS: Does anyone else have this problem or had this problem if so what have you tried.

Your rear O2's are probably unplugged or something, they have no effect on how the car runs though, so it's not your problem.

Maby it's just a natrual thing? lol What kinda hesitation are we talking about here?

Driving FaSSt

well the car didnt do it when I bought it so its something I did or somethings worn out now

But the cars down on power slightly and it will pull then stop for a split second then come on again.

actually now that I think of it its really around 3500 rpms (my bad)

P.S. This is my 2nd M6 LS1 I had one before the CHevelle and it didnt do it either, Hopefully I figure it out soon because doing this and that isnt good since I'm 17 and only make $6 bucks an hour part time and the fact that I pay for my own stuff including the car.

My MAF wires are fucked up and it does the same thing with the pull/studder/pull. It only does it ocassionally though and sets the SES code, which goes away after a few re-starts.

Mine doesnt do it all the time either just occasionally so you may have hit the nail on the head.

mines thrown a light as well but went away after 2 or 3 starts

I'll see if the mechanic will look at it for me

Set it on fire....

in response to what TheBlur said, did you perhaps port your MAF or have an aftermarket MAF? either way, maybe you should try cleaning your MAF and see if it goes away.

its stock and I did clean it and it didnt help

Get a couple new 02's and start there. I'd also check every connection that you unplugged, as there could be a problem there.

Get those codes cleared and see if they come back... that might give you a better idea as to what is going on, they could have been stored from who knows when.

Did you do new plugs after you seafoamed the car? If not, then I'd pull them and see what they look like. Was the fuel filter changed after the seafoam gas tank stuff what run thru?

The codes he is getting are for the rear o2's so getting new ones for them would not help anything. I agree with ^^^^ though, pull the plugs and see what they look like.

IT did it before the new plugs I thought that would fix it but it didnt so the seafaom probally didnt cause it.

I'm goin with Blur on the MAF thats next

BTW the things listed in the first post were to try and get rid of the stumble it had this before all of that

I have the same problem and it drives me insane, except my does it around 2800 rpm and I have an A4. I have already replaced the plugs...anything else that could cause it?

Driving FaSSt

I know I hate it when it does it. I went from loving the car to not so much anymore.

THe main thing that gets on my nerves is I want a Ram Air hood for it but need to get this fixed before I can save for the hood.
