Default Sticky throttle

Hello guys. I'm new to this forum stuff. Here's my issue. When I put initial pressure on the gas pedal it sticks or catches. I tried cleaning up the throttle body and looked under the dash to see if the pedal is hanging up. Still catching. Any suggestions would be great thanks.

What year is the car, if you have traction control make sure that the cable is in the groove of the throttle body, if it is all good with cable and you still have the problem with car running grab the body near cable and see if you can fell that tension snap/click that your feeling with your foot, if so reclean the throttle body with a rag and solvent/Carburetor cleaner

Sounds like something is causing the butterflies in the throttle body to stick. Could be a worn shaft in the TB

Ok....when I worked the throttle by hand I couldn't feel it catch like it does with my foot. I did notice the spring looks a little beat. Is it possible the cable might me shot? Some day it isn't as bad as others.

Unhook the throttle cable connection. Is it the throttle body binding or pedal/cable related?

Based on what I've done, I believe it is a cable or pedal issue. The TB didn't seem to catch when I activated it with my hand.

You need to check the throttle with the engine running. The throttle is most likely hanging up at idle when running due to the losd on the throttle shaft.

Now that makes sense, because it only happens when it is running. When it is off it doesn't catch. Thank you.
