Well here it is 11-05 and I haven't had the fuel sensor error now for a long time.
I think I'm on my 7th fill up with no error message. I've stuck with Chevron gas and I'v used Techron additive in about every third fill up and Sea Foam once. We've also been putting only Chevron in our newer GT, and have put in the Techron additive a few times in that one as well. Hopefully it will never have the sensor error.
Someone commented in this thread that They feel sorry for my bank account with two Stangs to mod, boy were they right on the money with that comment.
So many mods that I want for both cars, so little actual cash to do it with. I guess I'm going to have to get better at saving $

Hey at least I am driving my GT convertible every day, what a joy that is!

Future mods - We want to do both cars with cold air intake and tune. Louvers for back side windows on Green GT, Borla stingers for red GT Conv. Eventually Magna Charger supercharger for red GT...lovin it!
