hi all i have a 99 156 v6 and for some reason the red injector light appears on my dash and the fan comes on to cool the engine. performance is not affected and it will do this when hot or cold if i tun the engine off the fan goes off when restarted but the light stays on for a few miles before going off. this happens every 15 miles or so. does anyone know what is causing it or had this problem before. help apprieciated thanks karl
Hi i had same trouble had diag the lambadas changed temp switch in the thermo still light on even after diag and reset light again. In the end over xmas i took the MAF out cleaned it with carb cleaner and sprayed a load through the throttle body then did an ecu reset and throttle reset the light was still on then the next day the light went out and has stayed out since. Had a new thermo last week to and its running great now.
