check engine light

codes lead you in a direction, it does not define the needed part. thats why a diag costs money. make sure the wires to the injector are good and not broken or laying against anything. Roy

my 3.5l v6 was having same problem. check engine light on - especially during damp conditions. lots of inspections with diagnostic equipment failed to solve problem, finally found out that the boot between the top of the gas tank and the body of the vehicle was at fault. replaced it and have not had any more problems.
