Some times it doesnt start sometimes it shuts off when Im driving it ????

Sounds like the fuel pump is failing, have the pressure checked at start up.

Blower motor resistor is faulty.

Seems the VSS is faulty. Vehicle Speed Sensor. This sensor drives the speedo ( Odometer )

Since you've handled the usual suspects, I'd suspect the coil and/or power transistor in the distributor.

sound like you need a new blower motor.

I would start by replacing the Crank sensor and the cam sensor.

You may have a bad ignition switch.

Also replace the camshaft sensor and fuel filter.

Check the catalytic converter. If the carbon monoxide cant get out, it sometimes will act like this. It plugs up over time.

Has it ever been replaced??

I did mine about 2 months before I got rid of my Civic.

By the way, the exhaust system on most Hondas is the Welded, so you have to pull off the whole line from the back of the motor to the muffler.

Since you've replaced many of the usual suspects (fuel pump etc.) you might want to look into testing or simply replacing the crankshaft position sensor or the camshaft position sensor. If you intermittently lose one the these signals it would cause the problem you describe.
