i have a 95 gmc sonoma with the 2.2 5 speed. its a hydrolic clutch, but the pedal depresses to the floor very easily it has trouble going in and out of gears sometimes. also i have notice a loss of power when driving on the highway i can barely get 65 mph out of it. it got at least 75 mph a few weeks ago could the clutch be the reason?. its got 180000 miles.
