first 20 miles or so it runs smooth and strong. then it seems that i have to push the gas to keep up the speed and the motor bogs down as if it had an engine brake, like a truck. it goes away when accelerating it also goes away if i floor it and " clean the pipe" after a mile or so of drag racing the engine to about 4500 RPM it runs smooth again. could it be the filter?... i had the vacuum system checked and some tubes replaced. also used high grade fuel system cleaner. using premium gas. i dont drive the car much. it only has 88.900 miles and oilchanges are done regularly....jsut wondering if anyone else has these symptoms....
thanks,
Tom

start with the fuel filter. change it and run again. look for symptoms that occur during its bog down, IE, temp gauge, oil pressure, where you bought your gas. etc. filter might do the trick.
