Engine Performance problem
1987 Mercedes Benz 300dt 6 cyl Two Wheel Drive Automatic 112000 miles

Just changed the fuel filters but it still has no good power. Not real familiar with these cars, going up a hill and when I put it to the floor it dont seem to move any faster. The engine revs put its like its standing still. Loses power going up hill. Slow take off. Is it the fuel injectors, this year had problems with the turbo I heard. HELP!
