Evening all, I do all the diagnostic work for one of our local secondhand car dealers and he sells a great deal of Hyundai Accents, nearly always the single cam 1.5 models and about 80 percent or more of them at some point or other put on the MIL and nearly always the code is P1128 Fuel system lean part load. The cars always run perfectly but I always check the usual things , Lambda sensor switching, speed of switching, heater supply/resistance MAF output etc. and rarely find a fault and for a while now he has swopped the MAF and this often cures it, I have been suggesting to him that there might be a software update available and have checked archives but found nothing, has anyone come across this before please? Many thanks, Jim.
