I replaced the fuel filter, egr valve, and throtle position switch. I cleaned the mas sensor. The problem went away. It does'nt buck st high speeds any more, and mileage has increased. Within 5,000 mi, I've seemed to lose power and idles rough again, only when it warms up. My gas consuption has increased to 17-20 mpg, but I should be getting above 25 mpg. Once in a while I'll hear a hissing sound from the tailpipe. Can you help me?
