Question about 2003 Honda Accord
The two fault codes came up after I rewired the fuel injectors due to rats lunching on them. Checked but find no other wires. Idles up and down. suspect air leak. Idiot who worked on it before has mickey moused a few things. I fixed them but the engine light is on.

I think I would suspect the fuel injectors, especially since that is the code you are getting. Fuel injectors clog up, get dirty, stop working the way they should. They can be cleaned (you can remove them and send them to a company that cleans them and makes them like new, or, they can be cleaned in the car by some garages, or, you can get a can of Sea Foam spray and spray it into your throttle housing several times to try to do some cleaning that way, or, you can dump a can of Sea Foam (non-spray) into your gas tank and run it with the fuel through your injectors). You should probably check when you first start the car to see if you are getting any leakage from one or another injector (one or another may look moist or wet if the seals are leaking). You can also do the long screwdriver test (hold the bit of the screwdriver against each injector in turn and listen with your ear against the other end to see if each is clicking regularly). I would try the Sea Foam first.
I hope this is helpful in getting you started on a fix.

Testimonial: "Quick response and good suggestions. I have not yet verified the solution but believe that I'm troubleshooting in the right direction."
Unfortunately, there have been lots of cases of rodents chewing on car wiring. In the last five years or so, wire manufacturers have used soy beans as an ingredient in the insulation coating on automobile wiring,and it seems it is tasty to our small friends. Depending on where you park your car , will make you succeptible to it happening again. The Mom of a friend of mine had $1000 worth of damage to her car wiring, as some chipmunks had a field day with her newer car. She ended up placing some moth balls around where her car was parked, to keep the critters away. If you have wildlife near your car, look out!

Perform a valve clearance inspection and adjust if necessary. Tight or sticking valves will cause a misfire or rough running concern. Note: Perform valve adjustment when the engine is stone cold. 4cyl: INT 0.26mm EXH: 0.30mm (V6 engine are hydraulic and no adjust necessary.) Also check for a sticking or stuck open EGR valve. For diagnostic purposes only: Remove the EGR valve. Place a business card over the EGR passage and bolt the EGR valve back on. This plugs the EGR ports and if the misfire goes away the EGR valve is partially stuck open and is defective.
Check for low fuel pressure. Check for low compression. Check cam timing. Check for a weak ignition coil. Also don't over look the possibility of worn or broken engine mounts which cause excessive engine movement and engine vibration. -hope this helps
