Accelerator pedal won't press down on start-up Options

[MSKapcala]

So I have this weird issue, where occasionally, I start the car, let it warm up and get ready to drive and the accelerator pedal won't push down. I'm shifted into gear, but the pedal won't de-press. It's like it's stuck or something is under it (obviously it isn't). Only way it seems to rectify (and I'm not sure it helps), is if I open the engine and manually open the throttle body while in neutral a couple of times. Then if I keep playing with the pedal it finally gives presses and works fine.

Anyone else ever experience this? I have no idea what it could be. I also have a new accelerator cable. I feel like it happens a lot, if before I last turned off the car, I reversed (like into a parking a spot) and then shut off the car.

I also thought maybe the throttle body was getting stuck, like a vapor lock or something? Like pressure built up in the throttle body or something. It's weird. It happened yesterday so I got under the dash and looked at the pedal and where the cable connects... Nothing obstructing or anything like that. I have no idea...

Have you cleaned the throttle body? There can be gunk that sticks the throttle plate to the throttle bore that gets soft when hot and turns hard again when the car cools back down.

Or check your cable from gas pedal to throttle body

Thanks. The cable is new and i've cleaned the throttle body a couple of times, but maybe there was a lot of junk built up...
