95 chevy silverado was lacking power and poor gas miliage. Replaced the plugs,plug wires and fuel filter. Gained some lossed power but runs rough at 1500 rpm. But runs fine at higher rpms. Gas milage still bad.

Replace the Ignition Control Module (ICM). Easy job. It may solve all of your problems.

Thanks, I replaced the rotor,and the ignition control mudule. It seems to be running better with no rough idle. I will see if the fuel mileage improves. I hope with gas at 4 bucks a gallon here in so cal.

Good job. As we speak, my son is going to a concert at the Hollywood Bowl tonight. Tickets are outrageous, parking is $20, and gas is $4+. That's what you get out there.
