Agreed! sounds like the throttle cable is frayed. I just had mine break leaving me stuck in a busy intersection and having to be towed home. The pedal started sticking, but was only intermittent over the course of 3 days. I'd change the cable ASAP. The one I got from NAPA was horrible and required much modification to get to work, but this seems to be par for the course for the re-pops

. If you can find an NOS one I'd go for it, I simply didn't have the time to find one myself.
