I have a 1996 Honda Civic HX 5-speed. It's got a new battery. I gave it a tune-up & oil change: new plugs, wires, cap, rotor, air filter, oil filter & BOTH O2 sensors. The check engine light came on AGAIN after driving 55 miles. I'm still getting error codes P1164 & P0401!?! BTW, I'm getting roughly 30 mpg combined, but mostly highway.
