you can clean your maf with elec cleaner a 5 min job try it .. i did after spend a couple of grand on plugs and misc other stuff.. the cleaner cost two bucks at ace hardwear...

 

steve harris which wing is that on the car in your avatar?

 

Again, hope it is the MAF. yes it is expensive but less than putting Plugs.

 

I had a similar problem from 2500-4000 RPMs. It turn out to be a boost leak.

 

Sputtering?? Really?

Mine went away after replacing plugs. I've had nightmares with this issue between the MAF and plugs.

 

how much is it to change out all the plugs... labor & parts?

 

around $800 at the dealer.
$500 at a local shop.

$80 if you do it yourself. lol.

 

Hey Ari, what was the fix for your problem???

 

Haven't looked into it yet. But I can't repeat the sputtering issue now.

I put in 5 gallons of 100 octane last week just for kicks and the issue started when I filled up with 91 Octane the next time. I'm wondering if the computer just needed to back off timing?

 

Ari, mine did that sputtering for a split second thing off and on. Then after a while the CEL would come on...but never stayed on. Then it was time to change the plugs anyway but when I did, it needed 2 coil packs. So don't drive it too long in that condition. My aftermarket warranty covered it so I don't know exactly how much it was for just the plugs.

 

Sounds like Plugs now. Did you try to disconnect the MAF?

 

I was going to suggest gas. Went on a road trip Sunday and the car would lightly sputter @ >4000 RPM in 5th and 6th. Car dropped flat on its face. Had 91 in the car. Added a can of Torco and topped up with 94 and pulled hard to redline. Must have been pulling timing.
