4.3 litre engine, manual transmission. Intermittent problem, engine cold or hot - when accelerating through the gears the engine is often very slow to return to idle speed, making it awkward to drive. The engine revs always slow down eventually and it is driveable but unpleasant and seems bad for the clutch.

If it does, then replace the ECM. good success
