    Re: 95 sts acceleration problem

    For a while now my car has been hesitating, just not accelerating smoothly and running rough in the 55-65 mph range. Cleaned out the EGR and she runs much better. One of the easiest fixes I've ever done on this car. The images sure helped.

    Re: How To Clean The EGR Valve

    Such great info here. I've done the RPM/ Coolant Temp/Volts mod on my 94 Concours as well as cleaning the Throttle Body. Today we were out running errands and the car started running very rough. The cat was also getting hot. Stopped by the parts store and picked up an EGR Valve gasket and a can of Brake Cleaner. Pulled off the EGR, cleaned it and re-installed. Car is running smoother and has better throttle response than it ever had.
    A big "Thanks" to this forum and the people that contribute to it.
    A new EGR was $177-275 depending on the manufacturer. $7.49 for a can of cleaner and gasket worked out much better for my budget this week.
