How do I check my codes on my 88 Honda Accord LX-i with a fuel injected A20A3 with 4 Spd AOD. I have recently did a tune up which included replacing both o2 sensors, plugs, wires, cap rotor, coolant temp sensor and t-stat. When I drive it on cold mornings it throws a cel shortly after warming up then when I shut it down and start it back up there is no code and my manual dose not tell me how to check the codes. Thanks for any help you can give on this.

 

Isent you a PM about looking under the drivers seat from the rear floor board.
