Replying to: jewelsstang (Aug 14, 2006 3:32 pm) "They told me they replaced the Mass Air Flow Sensor. after the replacement- they road tested the care for 34 miles and with no avail, could not get it to duplicate anything. Well, So far, so good on the stalling, etc..."   My current car (not a Mustang) exhibited the exact SAME symptoms shortly after initial purchase (nearly stalling out when trying to accelerate; essentially just falling on it's face when I gave it gas and then suddenly going). Dealer's thought it was bad gas/wrong gas yada yada yada.   Finally they replaced the O2 sensor (essentially the same as your Mass Air Flow Sensor). The car IMMEDIATELY ran much much better and hasn't done the stalling thing again. And it's been 5-years and over a 100k miles since that O2 sensor was replaced.   Try to have a little faith.

Replying to: rorr (Aug 15, 2006 5:27 am) Well, AWESOME - I can say that the car does drive like it never drove before. No grabbing, stalling, dying, etc.... Hopefully I got lucky. Thanks

Replying to: rorr (Aug 15, 2006 5:27 am) For the record, a mass airflow sensor and an O2 sensor (oxygen sensor) are not the same thing. The MAS measures the volume of air going into the engine through the air filter, throttle body, intake manifold, etc. The O2 sensor measures the content of unburned fuel in the engine's exhaust.   A car with bad MAS typically runs really badly. I personally have never seen bad O2 sensors make a car run badly. (A bad O2 sensor will light the "check enging" light and can cause other problems like high emissions and cataltic converter damage, but the computers in the newer cars seem to keep the engine running smoothly via an "open loop" mode.)

Replying to: wrekrambler (Aug 17, 2006 6:20 am) Thank you for that. It sucks when you have these problems arise and as we are not all mechanics, it's tuff to trust anyone when they tell you numerous things in regards to what's wrong with the vehicle. I believe this MAS was the issue since day one because it seems to be a completely different animal now. Drives like a car now. All of the numerous issues are showing themselves. What a Relief.

Replying to: stangaholic (Jul 19, 2006 8:18 pm) I also have the same problem with the transmission. I have had it into the shop 3 times and they tell my there isn't anything wrong. But my 05 GT is going back to the shop on monday, again. i will let you know if they find anything, but don't hold your breathe.
#19 of 121 My Story of 05 Mustang by yellowstang Sep 30, 2006 (4:46 pm)
Got my 05 yellow mustang on 10/26/2004. GT Premium package. V8 auto. Had to. My 1999 got crushed by a tree. In 11/04 had major transmission fluid leak, 325 miles. Had to have cooler line repaired. In Aug of 05, with 5700 miles, brakes squealing. All 4 brake calipers had corrosion on them. Feb of 06, 9062 miles. Several problems. Car is getting worse. Transmission slips when starting from a complete stop. Dealer couldn't find anything wrong. Replaced a few parts. Interior trunk lock and linkage had to be replaced. Right front dashboard rattled and was very noisy. Dealer re adjusted dash. Rattle came back. The tires began to loose 5 to 10 lbs of air per week. Dealer said the inside of rims were oxidized and they cleaned them. That didn't last long. April of 06, 10,315 miles. Had to have car put on flat bed and towed into dealer. Electrical system went haywire. Couldn't start car but all lights on dash were blinking. Had to have new battery??? Also had same issues as in Feb of 06. All tires loosing air, rattle in dash getting worse, transmission still lurching from a stop. Dealer said all was fixed when i picked up car. Yeah right!!! August of 06, 12,413 miles. Same issues as before, trans slipping, tires loosing air, rattle in dash constant and the big one, engine grinds when starting. That one they had to replace the timing chain. At this time, dealer assured me that all other problems were fixed 100%.   As of today, the rattle in the dash is the worse it has ever been. All tires are still loosing air, have to keep a tire gauge with me at all times, and the trans still slips. I call customer service, that was a joke.   I also have the gas shut off problem which i will address when i take my car in on monday.   My car is going back to the shop on Monday. Anyone have any problems like this. Replies to this message: shepherd5619 (Jan 13, 2007 2:00 pm) steinbud (Feb 06, 2007 6:21 am) dandalton (Feb 06, 2007 8:48 am) cccompson (Mar 12, 2007 3:03 pm)

#21 of 121 98' Ford Mustang(automatic) by writchoice Oct 31, 2006 (10:23 am)
I have a 98' ford mustang automatic.The gauges on my dash are not working. This includes the speedometer, odometer, battery, oil,,etc. When I start the car the only lights that come on are the battery light and the theft light. I had my fuses checked pep boys and they checked fine. He tested them with the car on of course. Then I asked a friend of mine who is a mechanic and he said it could be the instrument panel fuse and it needs to be replaced. I lost my owner's manual so I'm not sure exactly what it looks like or where it is located. Can someone give me an idea. Also if it is not a fuse can anyone give me any ideas as to what else the problem could be.

#23 of 121 Courtesy Lights by marineway1 Nov 04, 2006 (2:31 pm)
Anybody have an idea why the map lights on the rear view mirror (05 convertible) would suddenly stay on? I assume there's a sensor or switch somewhere that signals the map lites that the door are both closed and to turn off in a few seconds' but suddenly they just stay on(key out, pushbuttons checked off). Had to pull the bulbs to keep the battery from running down until I can solve the problem. Help?
