Hey guys. Cruising at 1400-2000 RPM, with very light pressure on the accelerator pedal (like in rush hour -- you know, typical in LA), the engine throttle will cut off and on repeatedly, as if the engine is being fuel starved. The car acts like you've let out the clutch too fast.
Engine has ~40,000 miles [that MILES, you Canucks and EUnionists]. Recently tuned up.
Any thoughts? Is there a throttle position sensor that needs adjustment? Other ideas?
