Idle surge at stop almost sounds like a cam but wants to choke out and I do not have a cam 5'9 gas any ideas I put a ton of new parts in this fuel pump brake booster transmission was running fine then all of a sudden seem like it wanted to choke out when I started slowing down in traffic

 

Check the IAC well (back of throttle body) see if it's carbon built up. If it is clean it. Also could be a TPS. Have a scanner that can read basic live data?

 

Sounds like the IAC. Cheap fix.

 

Thanks guys I have already replaced the IAC and throttle position sensor still having the issue I do notice though when I look down under my throttle body that there is moist of some sort on the bottom of the plenum do I need to take the plenum out and clean reseal and could the vacuum leak be possible injector related because when it does suck vacuum it makes my throttle high

Plenum gasket failures are common issues with the gas motors.
