LOSS OF POWER

2003 Ford Mustang

Engine Performance problem
2003 Ford Mustang V8 Two Wheel Drive Manual 70,000 miles

I HAVE A 2003 MUSTANG MACH 1 5 SPEED. I RECENTLY REPLACED CLUTCH DUE TO THROW OUT BEARING FAILURE. AFTER DRIVING THE CAR A FEW DAYS THE PERFORMANCE DETERIORATED DRASTICLY. THE CAR HAS SERIOUS LOSS OF POWER AND USES AN INSANE AMOUNTOF FUEL. CHECK ENGINE LIGHT CAME ON AND POINTED FAULTY MASS AIR SENSOR. REPLACE IT ALONG WITH A FRESH SET OF PLUGS AND CAR SEEMS LIKE ITS NOT RUNNING ON ALL CYLINDERS BUT IDLES SMOOTHLY. NO CHECK ENGINE LIGHT SINCE REPLACING MASS AIR SENSOR BUT WHEN I DRIVE IT ON HIGHWAY THE CHECK ENGINE LIGHT COMES ON FLASHES QUICKLY AND THE TURNS OFF. IT DOES IT PERIODICALLY. IM AT A LOSS AND CANT FIGURE IT OUT.
