I've got a 350tpi that runs extremely rich until warmed up ,but after its warmed up doesn't run as rich.this is in a streetrod with no cats,no mass air ,but it does have map.also there is no ninth injector for cold start.would appreciate it if someone can point me somewhere or to someone knowlegable with the tpi motor.i don't want to just start replacing parts.i could use an obd reader to see if there are any codes but I can't drive it to an autozone in this weather. thanks !
