The throttle has been getting stuck, sometimes full throttle when passing. Did Honda ever have a recall on this problem? What could it be, seems mechanical on the TB but I can't figure it out. When it does stick the ignition has to be turned off, pull over and physically push on it to undo it. However, it doesn't take much pressure. It's really dangerous.

 

does the butterfly open freely when you push on it or is there some resistance? could your throttle body be dirty?

if it is just buy some throttle body cleaner, spray the butterfly then clean it up. hope this helps and good luck.

 

Yes it is very free and with little resistance; however, at the same time it is very dirty so I'll use some carb cleaner (ok?) to spray on the spring and...

Oh, you mean the butterfly inside is what is getting stuck? Not the spring and assembly on the outside?

 

Either one could be getting stuck. You'll have to look & see. Also might be sticking inside the cable itself. Maybe even a pivot pin messed up on the pedal itself. Or a broken return spring on the throttlebody? Unhook the cable at each end, so you can work each part individually. Sometimes that's the only way to figure out which part is NOT moving freely.

Whatever's dirty, for sure clean it up. One of the more common places for it to stick is where the butterfly *almost* touches the wall inside the throttlebody. But that would usually stick closed, not open.

 

I dont know if this is the same sounds like it, When the car first starts up the throttle sticks its a known honda issues to do with the Throttle body the fix is simple. You have to take the throttle body and clean it. From what I undertstand its important you use the right cleaning solution and your not suppose to spray on one of the plenum or something>? I have a body that works at Honda and told me thats all i needed to do. Call your local dealership up and speak to someone that knows or works on the cars there.

 

Perhaps that info can help others but in my case it only sticks in full throttle.
