This would point to the TPS (Throtle Position Sensor) and IVS (Idle Validation Switch) both part of the Go Pedal Assembly ... but someone else probably has more knowledge of this and help you fix it..

Wouldn't the TPS throw a SES light if it goes through the computer? I don't know just a thought I don't have any new codes

Just something I've heard, trouble codes sometimes only come on when there is a problem that is causing emission problems. It could miss like crazy and if there are no bad emissions caused (not likely ...but), no codes would come up.

P0220 - IVS - Throttle switch B circuit malfunction - Short/open circuit, switch failure, operator, PCM
P0221 - AP/IVS - Throttle switch B circuit performance - Failed pedal assemblyThese are the only codes I found for the TPS. They may not set with what feels like a "dead spot". The TPS is just a potentiometer and the PCM may not be able to discern a dead spot from tapping on the pedal.
Here's some info about TPS replacement. LINK
FYI : The IVS contacts are normaly open and close to signal "off idle" to PCM when pressure is applied to the throttle pedal. If the IVS contacts do not close the PCM ignores any TPS signals.

You don't have to take the whole assembly out to change the TPS if you have a separate IVS. See the link I posted.
