I GOT THIS INFO FROM ANOTHER FORUM AND JUST WANTED TO PASS IT ALONG.
FORGIVE ME IF YOU ALREADY KNOW ABOUT THIS (COPY AND PASTE)
This just came out from ford.
6408 - 2007 SHELBY GT 500 MUSTANG - DRIVABILITY CONCERNS - AIR FILTER
SOME 2007 SHELBY GT 500 VEHICLES BUILT BEFORE 09/01/2006 MAY EXPERIENCE DRIVABILITY CONCERNS INCLUDING: ROUGH IDLE, A SURGE AT LESS THAN 2000 RPM, A LACK OF POWER AND ERRATIC READINGS ON THE BOOST GAUGE. THIS ISSUE MAY OR MAY NOT FLAG A DIAGNOSTIC TROUBLE CODES (DTC) IN THE POWER TRAIN CONTROL MODULE (PCM). THESE SYMPTOMS MAY BE DUE TO A QUALITY ISSUE WITH THE AIR FILTER ELEMENT. TO CORRECT THIS CONCERN, REPLACE THE AIR FILTER ELEMENT WITH PART NUMBER 7R3Z-9601-AA (MOTORCRAFT FA 1807).
Now here is a copy of my post regarding my car and the trouble I had with it today.
Thanks for the info on this, I would have freaked out if I did't read this post recently BECAUSE:
My car was built prior to 09/01/06 and I now have about 1800 miles on it.
I drove it to work yesterday (about 65 miles one way) and it drove absolutely unreal (as usual) and believe me, I DON"T BABY MY CAR !!!
On the way home from work this morning (worked a 24 hour shift) it ran fine until I got about 10 miles from home and all of a sudden it felt like my car was running on 5 or 6 cylinders, no warning lights came on, it was barely running and I thought it was going to die right there in the middle of the road.
Had I not read this thread I would have thought that my world was over for a while but not to worry, just an air filter huh (I hope so!)
I limped it home and parked it in the garage and it died right there without me even turning the key off.
So tomorrow I will drive (my F-350) to the Ford dealer and buy a air filter (if they even have one in stock) and slap it in and pray that when I start it all will be back to normal again!
Jeez you would think that after making cars, trucks and air filters for the last 100 years they would not have any more trouble with things like this.... unbelievable.
Anyway thanks for the post and I will update with the results as soon as I can get another filter and test drive it again.
On a side note: For those of us who will be changing over to an aftermarket CAI soon, you might want to consider still getting a new filter for your stock housing prior to taking it into the dealer for any warranty work since they may atribute some of any or all of your troubles to this air filter problem should you simply put the old filter back in prior to taking in the car (just a thought).
Anyone else experience any trouble like this due to the air filter?
(BELOW is from another post on same forum)
The explaination that was given to me was that the filter was causing turbulence in the airflow past the MAS, and the computer was interpreting this as a lean condition, when in fact it was not. We had found the spark plugs to be black, indication that it was overcompensating and running rich. I was able to put about 15 miles on the car after I had the filter changed, but it is parked now for the winter, so hopefully this fully cured the problem. I'll probably be replacing the filter with a CAI in the spring, but it is good to know that there are no other problems before I change over.
UPDATE: Local Ford Parts Dept: "No we don't carry that filter and we can't order one because we have to buy them in bulk and we don't want to get stuck with the rest of them." Have a nice day! Now I got a 07 GT500 sitting in my garage and I can't even run it!! ... WTF ???
Okay dealer parts dept. called me back and said that they are going to order the part for me but I have to wait a while for it to come in and my car is just there sitting collecting dust - BUMMER!
I should have made FORD pay for the tow (about 70 miles to the nearest dealer) and the air filter but I'm just such a nice guy - I'm gonna do it myself to save them some money (and avoid everyone and their mother test driving my car while it's at the dealer service dept.)
Oh yea, the filter is 58.** plus double freight (about 98.00 or so total to my island), I could've bought half an intake for that!
