Just changed the timing belt, cap, rotor, water pump, plugs, gear oil, rear oil, oil, filter, belt tensioner, guibo, rear tranny seal, thermostat, air and fuel filter and the trunk roundel. The car is now more sluggish in low gears than it used to be. Fine at 65-70 mph. Is all the extra friction from the new parts sapping that much power. Runs good but not quite as fast a before. TIA.
