Misfire when cold with six CEL codes
I have a 2001 CR-V that I recently purchased. Someone had rigged the CEL and jumped it to the battery light to make it seem like everything was good.
When I first start it in the morning, it runs rough, misfires, and tries to die. I hold the gas at about 2000 for about 1.5 minutes and then something happens (like something turns on or off, sensor??) and then it runs great. CEL codes P0301,P0302,P0303,P0304,P0300,P1399. I've done the following:
Replaced plugs, wires, rotor, cap
Checked timing
Adjusted valves
Checked compression (200+- on all cylinders)
Replaced O2 sensor
Replaced catalytic converter
It's weird that it only runs bad when cold and perfect after about a minutes.
Any advice would be great! Thank you!

Re: Misfire when cold with six CEL codes
Did you check the function of the FIT and IAC valves? Did you check the fuel filter? Did you check the fuel pressure? And why are you throwing parts at it before troubleshooting and identifying the root cause, hoping to get lucky, or just have a lot of money to burn? LOL JK
Also, are you using the right plugs: NGK ZFR6F-11 V-power
