TW chip stuck on one tune

I dont change tunes very often, so im not sure how long its been stuck. If i mess with the knob sometimes it will start working.....well i have having throttle pedal problems intermittently as well, so I thought they were related. After pulling the codes and replacing throttle and cam positions sensors, the chip is still stuck in tune #1. I removed the chip, ran the truck, re installed the chip, and it worked fine for a cpl days then no more changin tunes.

Any suggestions?

That was my first thought. chip was seated well when i took it out, tape was still in place. re seated and re-taped when i put it back in.

you might try re-cleaning the PCm....use a small amount of your wife's (girlfriend's), fingernail acetone......might have a bit of crud still on it.... ?

or you could unplug the knob from the chip, give the knob internals a squirt of Electrical Contact Cleaner, work it all one way, and then back 40-50 times, squirting it once inna while and clean it,
the make sure it's DRY and try plugging it back in then....

you can also borrow one (knob and cable) from your buddy and unplug yours from the chip and plug his in, if it works then, it's your knob switch....
