Agreed, check for codes first as theres a few possible causes. It could well be the cold start injector/it's wiring if the problems are related. best way to really prove it out is to remove it's fuel feed (and blank off obviously!) as just pulling the connector doesn't account for a leaking tit, but definitely pull codes first off (while running as some like AFM disappear when its off) and check any result against-: http://www.cygnusx1.net/Supra/Librar...aspx?S=FI&P=26
