I've had the same exact problem on several occassions. I'll be stopped and hear the rpm's rising. At first, I couldn't understand what was happening. It's real easy to be on the brake and lightly touching the gas at the same time.

 

Sounds like the IAC valve. This used to happen in my contour all the time. I replaced the IAC and the throttle position sensor wiring harness, and it was fine.

 

I too am thinking Boomer was slightly touching the gas pedal while pressing on the brake. It's easy to do no matter how familiar a person is with their pedals and it's hard to feel it since you are already pressing on the brake. I also agree with Grantsdale(I figured this would happen sooner or later ) about the sudden acceleration being driver induced. People have a tendency to panic when something unexpected happens and get brain freeze.

Me three :bang:

Boomer you tapped the gas pedal, man. I did the same thing two or three times the first week I had the car. Only realized I was causing the problem when I looked down and saw how easy it was to inadvertantly hit both pedals.

 

Yup, and they were all found to be operator error, hitting the gas instead of the brake.

There has never been a confirmed report of an accelerator sticking, and no recalls issued ever. Operator error 4tw.

Exactly, if you only had light pressure on the pedal, if it 'stuck' it would not be with the force required to go through the wall(since you never floored it in the first place). Conversely, doing a brake stand burnout shows that with auto or stick, you can hold the car in place even at full throttle with the brake pedal-its actually hard for an auto to over-power the front brakes from slow speeds without a very forcefull effort on the thottle. Pulling into a garage? how much pedal pressure could possibly be done? They weren't paying attention, noticed the car moving, and panic-pressed the 'brake' pedal . The deceleration of a moving car is exponentially more energy then stopping a full throttle car from going forward-the brakes are more powerfull then all possible available traction. Conclusion, another greedy idiot wants something from someone for their own stupidity.

Especially with thick-soled or heavy treaded shoes where you can not feel the pressure, or habitually place your feet in regards to where your daily dress shoes normally 'end'. People move their seat 1/2" to make the pedals comfortable, then add 3/4" of shoe sole with no adjustments, especially with 'stompers', high-heels, foul-weather boots, or even some high-arched cross-trainers.

 

On my 86 GT..If I recall correctly..There was a throttle control sensor..I'd cleaned out the engine bay with a steam clearer..then when I was driving the car up the freeway it took off on it's own..from 60mph to 90+mph I pushed in the clutch and the motor just zinged..let the clutch back out and used the brakes to slow it down..got it down to a resonable speed and turned the motor off and restarted it and it went back to normal but 5 mile later it did it again..found out I'd messed up the the throttle control sensor with the water..75.00 bucks later and three min's to change it out it was back to normal.. Just wonder if there is one in the 05's that could be suspect

 

I heard that if you dont drop the clutch and do a burn out every now and then,that the onboard computer gets a little grumby and turns on "auto burnout mode"...something to do with some guy named shelby....

 

I had this happen yesterday. (Not the driving throught the garage part... the revving part) I looked down and my aftermarket floormat had crept up just enough to contact the accelerator, which stopped it from being released all the way. As a result, I downshifted and came to a stop, but when I put in the clutch the engine revved up.

...just my experience...

 

I have experienced in my car before what I thought was a stuck pedal. Turned out to be the darn floor mat edge catching the back of the pedal where it goes through the firewall. it didnt race off or anything just kept the engine up from idle. I also have a 99 taurus that when I first bought it the cable was sticking. You would step down to accelerate and it had a spot where it would stick. They supposedly tossed some lube or graphite in the cable housing. It worked for a while and would come back now and again. My wife drives it now and when it acts up I take it out for a spin and stomp the sh*t out of the pedal repeatedly and it seems to clear it up

 

I'm telling you- I don't have my stang yet, but if the cruise control buttons are on the wheel, then he must of set it by mistake at the same point he put the cluth in.

I've done this with my Probe GT - it's not easy to do, but it can happen.

 

Hey guys, able to hop on for a sec at work.

I'm reading all your replies, and I thank you for the sleuthing, but.....
we're forgetting one thing.

I'm on an incline...in neutral with foot on the brake. The foot is not moving, and the RPMs go up when the clutch is depressed.
If it was an issue with my foot on the accelerator....the RPMs would be rising regardless of clutch depression. It ONLY happened when the clutch was in.

Normally....
-if you hold your foot on the gas while in neutral .... it will rev
-if you do the same with clutch depressed....it will rev

Thats why it was so weird...
Any idea's???

I've done it too, not in my GT cause I don't have it yet. But in my husband's 1994 Escort he drives to and from work. I just pressed the brake harder, and also the gas (that's how I figured out what I had done) the car still stopped. I've done this about 4 times now, kind of annoying, but now I know to move my foot a little to the left before pressing on the brake harder. This has never happened to me in our 2002 F-150 Crew Cab, which I've been driving since I sold my van to get the GT.

Maybe the manufacturer's should increase the distance between the gas pedal and brake pedal in their cars?

 

I have a stick as well, and i've had this happen.
But with mine, it doesn't continue to rise.
It goes up to about 2700rpms and then falls to the
normal amount. Doesn't happen all the time, but enough to
notice it.
And I've paid very close attention when its happened. I don't have my foot on the gas OR the brake. (flat road)

But seriously... get it checked out, Boomer. If there's a problem with the electronic throttle body, I'm sure we'd all like to know. Besies, it could become a safety issue at the wrong time/place. You've got it warranted, no harm in getting it checked out.

Only time I saw a stuck throttle was on one of those racing crash videos. It was called "...And They Walked Away." He had been tapping a guy's rear and I guess he screwed something up because after one of these taps his throttle decided to stick itself to the floor and he flew through a retaining wall of tires, up a steep incline, and into the woods. BUT, as the tag line of the video said, he walked away!

 

LMAO...

 

hey bookemdano,

Had it only happen once?
Yeah I'm keeping an eye on it..

 

The only thing I can think of is that when your engine is cold when you first start it ,it goes to high idle and when it warms up it drops down to about 900 RPM .If you started you car and started driving for a bit it could still be on high idle untill you stop for a good bit and let the engine warm up the sensor to let it drop off .
If you use the cluch you are putting a load on the motor and this would bring the rpm's down untill the cluch is released ...raising it back up to "Cold Idle" if the engine has not got warm enough yet.

My S-10 is like this ...if I do not let it warm up and let the idle come down before I go ...when I come to the first stop on my trip I release the cluch and it goes back to high idle untill the sensor warms up at the stop light ,then it drops off.

 

Thanks Craig,
Unforunately this was after a 2 hour drive (220km)

Drove it for another 30 minutes to get to my destination..no problems.

Its weird I know.

 

ive noticed once or twice while downshifting the rpms raised by themselves to sorta rev match for the next gear. it has only happened maybe 4 times and ive definatly looked to see if i was hitting the gas pedal. it happens only when im depressing the clutch and hitting the brake at the same time and very randomly at that. never just the brake alone and ive never seen it higher than 1500 rpms either
