A bad AMM can cause a lean running condition, lopy idle, a no start, runs but has no power, random stalling, or any other strange running conditions. This is CHEAP compared with a genuine new or rebuilt, even at wholesale prices! Don't buy the china-made aftermarket units. 1/2 the time they are not even built to the correct specifications and often fail shortly after instillation. Stick with a genuine unit, good used units are still Pierburg original quality!
