I got a 2002 Chevy TrailBlazer LT 4WD and it runs fine when cold but as soon as it warms up when you are sitting and idling it is fine but when you got to push on the gas to move the engine stutters and sometimes shuts off immediately and will continue to do so for the remainder that the engine is warm. Anyone had this problem before or know what could be causing it?

 

Maybe a problem with the throttle position sensor ?

 

It could be, Had a guy with a computer hook up to it but it wasn't throwing codes. He recommended replacing the Camshaft Position Censor saying that is a common problem that will cause it.

 

Just threw some codes today they are P0420 P0128 and P0014

 

Guy bought the car from hooked it up to a professional machine and cleared all of the codes in the data stream. He said they put new cam sensor and actuator on before they sold it but now it is throwing the code P0340.
