Hi I hava a 95 sts and when the car is cold it runs very well(churps tires when shifting into second gear)but after I run it hard for awhile she doesn't take off fast at all...She takes off slow and smooth until it hits around 60 mph then the she revs out like normal!!!What the heck could be my problem?I know I havent driven the car in awhile and the gas might be not the best...could that be the problem(I gum'd up the injectors or fuel delivery components?Anything to help me out would be great...Thanks a bunch.

 

I actually found out today it runs slow out of the hole all the time now!!!It pics up good when it gets around 40 mph and on but what happend to the crazy bottom end,tire chirpin,300 hp car that I once knew?Please let me know whats up with my baby!!!Anything would be great!!!!!

 

To figure out if it's the fuel regulator that is on the fuel rail that was my problem and I switched mine to a brand new one which was 40 bucks and it worked
