check your ignition timing mate ive had the same problem for about a year, changed allsorts trying to sort it, but it was the same. check the ignition timing by bridging all the 3 terminals together on the tps wire (throttle position sensor) to get it to idle lower than normal in oder to time the ignition. Then use a strobe light and line up the timing marks by turning the distributor. this worked for me could hear an instant change on tickover and the eml went out permantley and its restored lost power.
