Sticky gas pedal....not the recall type - Toyota Nation Forum : Toyota Car and Truck Forums

Hi everyone,
First off my sticky gas pedal is in no way related to the recent Toyota recall issue of WOT stuck pedals. My 2000 CE 4 cyl has recently developed a sticky gas pedal. When I go to push on it like when taking off from a stop sign I can feel a little resistance and then it will snap down a little and be fine. This is kinda hard to explain....kind of like a stick and slip situation. It is really noticable when only trying to give it a small amount of throttle,,,,like when trying to creep foreward a little. I am thinking the cable needs lubed but after looking at it there seems to be no good way to lube this cable.

Anyone have this issue?. My wife has noticed the stick also. What do I need to do to fix this thing?

Please help and thank you in advance.

clean your tb, just pull the intake tube and spray her out, may use an old tooth brush too if you have one laying around

tb is the throttle body.

Ask for throttle body or intake cleaner in a spray can.

I don't think the throttle body itself would be affecting it. Have you checked the spring on the butterfly valve(at the TB)?

You could try disconnecting the cable from the throttle and spray some lube down it. Alternatively, you can go to a motorcycle parts store and purchase a 'cable luber'. It a little bit of metal that you attach to the cable end. You spray lube into an opening on the luber and it gets it down into the housing. Step on the pedal to work it in a bit and see how it goes from there.

From past experience, this a classic case of the butterfly valve needing to be cleaned inside the throttlebody. A thorough cleaning inside the TB around the butterfly valve should fix this. Follow the how-to guide.

What he said. Seen this several times on several vehicles. A little carb or tb cleaner and toothbrush will fix it right up. The problem is a small ring of gunk that builds up where the butterfly valve rests against the inside of the tb. It makes the valve stick and gives you a little resistance when you first press the pedal.

What they said. The crankcase vapors are sucked into the TB and cool off causing gum to form. This is something that our cars do.

My dealer took care of this for me when I brought it in for an oil change. It has been about 4 years since I had this problem. They told me it was because of the type of fuel we use around here.
