My gas pedal does not seem to have the same smooth travel that it used to have. It feels like it's "sticky". I noticed this feeling after finally installing a rebuilt ABS module. I've been driving with a different ABS module that was bad.

Could these be related?

 

No,

most sticky pedals are gummed up throttle bodys, take it off and clean with carb cleaner and reinstall you will need a new gaskit or gaskit making material to make your own I clean mine every 3rd oil change and you will not have anymore problems as long as you do a regular cleaning

 

Are there instructions posted for removing the throttle body. I removed the ring clamp on the big hose, but i couldn't pull the hose off the assembly. Assuming I can pull that off, what other things do I have to unscrew, remove to take off the throttle body.

My car has been getting harder to start, and after starting, it seems like pushing the gas isn't as responsive until I drive for about half a mile ...

 

My gas pedal was sticky, I was going to clean the throttle body, but decided to spray Wd-40 on the throttle cable instead. I sprayed the cable, wherever its exposed, the gas pedal felt great afterwards. Try it before you remove the throttle body.

 

Yoman, what year and model car do you have?
