The injector warning light on my 98 Marea SXTD100 has started going on and off recently. Have tried injector cleaner as suggested in most of the forums but no good. It appears at first start up and stays on until I have accelerated for a few seconds then comes back on as I change gear and the revs drop. Once it is off I can travel at a constant speed and the light stays off but as soon as I decelerate it comes on again. No big loss in performance, minor smoke but nothing to worry about. I have reseated all the connectors I could find. Anyone got any ideas ?
