Engine runs rough with engine light on. ETM failure. replaced with xemodex aftermaket ETM. runs good. What fails is the variable resistor potentioneter that measures the butterfly valve position. the Xemodex has designed this out and uses a magnetic sensor which does not fail. theirs is guarranteed for life.
