I have a 1989 Honda Accord LX 5 speed. The car runs fine until it warms up and then the car looses all power. I just got done replaced the exhaust system from the exhaust manifold to just before the muffler. I also went as far as replacing the oxygen sensor, spark plugs & wires, distributor cap and rotor, and the fuel filters.

Does any one have any ideas what could be wrong.
