my 95 gt has been having some fuel problems lately. it satrted out only having high rpm 4,000-6,000 range problems where it just satrted surging. no it does it at low rpms also. i took it into the shop and the replaced the fuel pump, and did this 3 step fuel system cleaning thing that was supposed to clean the injectors out. i replaced the fuel filter allready recently. Does and one have any idea what this could be? Thanks for all your help.

are you certain its a fuel problem? do you know what the fuel pressure is doing when you start surging? have you checked to make sure none of the injectors are leaking?

yea i had the guys at the shop check my fuel pressure and thats why they replaced the fuel pump. i havent checked if the fuel injectors are leaking yet, so ill have to get that done. they also said at the shop they didnt think it was the fuel pressure regualtor because they rarely see them go out so i have no idea what the problem is.

Adjustable fpr's are not that much. I would go ahead and take this opportunity to bolt one on.
