CHEVY SURGING

2005 Chevrolet Colorado

Engine Mechanical problem
2005 Chevy Colorado 6 cyl Two Wheel Drive Manual 124472 miles

My chevy is surging. This does not happen continuously. Only happens sometimes. I have replaced the fuel filter as well as add some additive that I was told that it will cleam my valves.

This helped but the surging is still occuring. It is also idling weird. Then it idles aroundd 800 rpm then it will drop to nearly stalling. I have to ref the car from not stalling all the way.
