okay first my DISCLAIMER: i realize that habitually stepping on the pedal/flooring the gas pedal/putting the 'pedal to the metal' is not a good habit to develop/practice- i unfortunately have this habit as all of my cars are over or well over 300HP and are either V6's/V8's....and sometimes that sudden burst of speed can really come in handy!....it is what it is
PROBLEM (only happening on my 2nd gen. 2009 MDX- on all other vehicles- Audi sedan and Mercedes SUV- gas pedal can be readily floored/stepped upon aggressively with no issues):
On two occasions in the past year, my 2009 MDX gas pedal has become stuck (WHILE driving!!!), immediately after floored the pedal ( which in turn was likely motivated by either defensive driving and/or road rage- albeit and unfortunately probably more b/c of the latter scenario) necessitating that I immediately step on the brake pedal (all while I hear the MDX accelerator still trying to kick in) to slow my accelerating (automatic) MDX down to a complete stop (again while accelerator is still revving up on its own!) so that I can shift to PARK and then quickly disengage the engine by turning it off with the key- it is ONLY at this particular point, while my 2nd gen. MDX is sitting (engine off) along the side off the road, that I can press/depress my foot down on the gas pedal as needed to manually release the stuck pedal!!!....immediately after this has been done, I can then put the key back in the engine, start it up, and drive away normally....CRAZY right?!!!!!
SYMPTOM
The only (relative) error code that my MDX has recently generated (and which I've since cleared myself using one of those OBDII scanners from Amazon) is the CHECK EMISSIONS error for which one of the steatlerships had stated that my O2 sensor(s) had to be replaced (about a $400 job)- could there be any possible relation to this bad 'O2' sensor that requires replacement and my MDX's gas pedal sticking (immediately after having floored it to accelerate quickly?)....
This problem does not occur often, in fact it will ONLY occur after having immediately floored the pedal (which I've done a good job of not doing that much)- so (instead of advising me NOT to floor my pedal) can anyone please recommend a fix/troubleshooting step/DIY maintenance that can be done to address this SCARY and potentially LIFE THREATENING 2nd generation Acura MDX stuck gas pedal problem?!!!! :|
I did consult the GOOGLES and found this below (which I'm likely not going to do myself, and would be completely willing to have the STEALERSHIP do- I wonder that those bastards would charge me?! :surprise:...scary thought!!!)

How to Repair a Stuck Accelerator Pedal
What You'll Need
Throttle body cleaner Screwdriver Toothbrush
Driving a vehicle can be fun if you have a perfect accelerator pedal. When these pedals stick it can cause danger for the driver and his/her passengers. Here is how you can repair this problem:
Step 1 - Checking the Accelerator Pedal
Before you begin to cleanse the vehicle of this problem you must double check the accelerator pedal in order to be sure there is a problem. Drive your vehicle around your yard a few times and push down on the pedal gently. Always be ready to brake in case it does have a sticking problem. Don't be afraid to test your vehicle at home first before getting onto the road. This will save you from any dangers that could happen once you are on the highway. Past news stories have often linked accidents on sticking accelerator pedals. Tragedies can often be avoided when we take the time to check things out. If the accelerator sticks then it is time to solve the problem.
Step 2 - Gathering Your Repair Tools
Next you will begin the task of repairing your sticking accelerator pedal. You must first have all of your tools on hand. Be sure that your body cleanser, screwdriver and toothbrush are close by. You will need these items to properly repair the problem. You can also wear work gloves to prevent any damage or dirt from getting on your hands.
Step 3 - Using the Throttle Body Cleaner
It is very important to not use a carburetor cleaner or silicone to fix the problem since these may damage your oxygen sensors. Once you have lifted the hood up you will remove the air intake hose. You will use your screwdriver to do this part. Once you have loosened the clamp on the air intake hose you are almost ready for business. On older vehicles you will remove the breather cover in order to reach the carburetor.
Once you have done this you will open the valve on the carburetor. Begin to spray a heavy amount of the throttle body cleaner onto a cloth and clean the whole area. You will also use a toothbrush or small brush to get to the difficult locations. Remember to be generous with the spray since it will help the outcome of your accelerator acting properly on the road. Be sure to wipe the throttle body as clean as possible and repeat the process several times. You may then spray the butterfly valve until it is well lubed. The valve will be more efficient after this cleaning. Everything will operate better with the swipes of the cleaner.
Step 4 - Placing Everything Back into Place
Once the cleaning is done you will put the intake hose or breather back into its' proper place. Turn on your vehicle and run it for about 15 minutes. this will get rid of the excess cleaner that was left behind. Try stepping on your pedal again. After doing these tasks your pedal should be in good working order
