Super sticky gas pedal. What can I clean?

My gas pedal is sticking really bad. Every time I apply brakes and then try to press the gas pedal, it's stuck and I have to press pretty hard to get it unstuck. It also gets stuck when I quickly let go of the gas pedal. I'm guessing it's because of vacuum pushing the plate closed.

I cleaned the throttle plate and it's not helping at all. What else can I clean?

This thread and this, the guy took off his throttle. Is that easy to do? Manual looks like replace like 4-5 gaskets.

Any suggestions what best to do?

check the spring above the pedal... theres not a lot it could be. infact, use your hand to move the butterfly valve, if it's not sticky there then you know the problem is between the pedal and the TB. all it is is a cable connected to the pedal so it shouldnt be hard to find the problem

Another possible cause is a frayed cable.

To check for this, disconnect the TB end and get somebody to push the pedal while you try to pull the cable back out. It should slide smoothly with almost no resistance, if there's a 'scratchy' feeling when you pull the cable back it will need to be replaced.

X2.

Exactly what I was going to tell you. Most likely you need a new cable. Not expensive or hard to install. The hardest part is getting under the dash if you are fat like me.

Re: Super sticky gas pedal. What can I clean?

Today I took off the throttle body and cleaned and cleaned it. Used Gumout Intake Cleaner and an old toothbrush. The coolant lines were too in there to get them out so I had to clean it with the coolant lines attached. There is one gasket to replace and it costs $2.50 (throttle body gasket).

Anyway, it didn't work. The plate is still sticking! I probably could have done a better job taking the throttle body out but then I might damage the coolant lines or at least have to bleed the coolant lines.

The manual says replace throttle body if sticking or binding (11-140). I guess I will have to wait till winter is over to work on this. All aftermarket throttle bodies don't have coolant lines and it's probably not safe in Michigan to use that.

There were some black stuff still there but they wouldn't come out no matter how hard I scrubbed.

The main problem is that the coolant seems to heat up the stuff that sticks and the vacuum line in there really pulls the throttle shut. Then, it's ankle hurting throttle plate stuckage.
