Well i have a D series 96 civic coupe. I removed all of my ac components today so i can install my turbo kit. All of the AC lines, ac pulley, and compressor from off of the block. As soon as i started up the car i am now throwing codes 41, 43, and 7. (oxygen sensor heater, tps sensor, and fuel supply sytem) Why would removing the ac from my car make me throw these codes?? I only touched ac components. The only electrical things i had to unplug were my condenser (round grey plug) and 2 other plugs... one was located on my ac fan and one was connected to a plug which came from behind my driver side headlight. This plug is now un connected and just sitting there. I figured these were the wires to turn on my fan and to make the compressor turn on. MY CAR RUNS LIKE CRAP!!! PLEASE HELP.

 

?

 

Some of those wires may have daisy chained to other things, so you may not be getting power or ground to something. I have no idea really, but that's a hunch...
