Faulty TPS

[awd-drifter]

Hey all. I'm wondering if I have a faulty Throttle Positioning Sensor or another issue. It seems that everytime the car is fully warmed up, after I put it into neutral before a stop and the car wants to die. It doesn't even stay on idle.

For example; the car is warmed up, come to a stop sign, throw it into neutral and the car will immediatlely lose rev and die and the only reason it doesn't die is if I give it some gas, than it will keep idle (kinda used to doing this now and not letting the car die by itself). The reason why I'm suspecting the TPS is because I've replaced the ISC already, triple checked my vacuum lines (no cracks), no boost leaks. The CEL also comes up when I'm in 'cruise control' and then when I drive, the CEL disappears when I let go of the gas pedal (car is still in gear and moving at highway speed). So, could this be a faulty/dirty TPS?
