I have a 93 Honda Civic LX Automatic. The car does not accelerate past 60mph, it feels like it's losing power. I replaced the fuel filter, air filter, and spark plugs. Any advice will be appreciated.

. Check engine compression--you may have a blown head gasket or leaking valves.
. Check for clogged catalytic converter.
. Check for vacuum leaks.
. Replace Ignition Control Module, coil, rotor, and distributor cap.
. Check spark plug wire resistance.
. Add fuel injector cleaner.
. Check engine timing.
. Change transmission fluid.
