Default New Codes on Disco 2!!!!!!

I just got codes 1300, 0150, 0304, 306, 302, 308
I know these are cylinder misfires on cyl. 4, 6, 2, 8, and a front right bank 02 sensor, but what can be causing the misfires, just recently changed all wires to 7mm magnecors and new bosch platinum 4s sparkplugs????? When i'm riding on the highway engine seems fine, only when coming to a stop/idle that the engine fluctuates and engine light starts to blink. Help!!!!

Could it be the coil packs, but wouldn't the other cylinders be misfiring as well....

Just looked at plugs in cylinder 4 6 2 8 and they were a little sootie, I think i'm running a little rich. Whats my next plan of action??? This started happening after I switched to bosch plat plus 4's, coincidence? or should I have stayed with the champions? Also need a new front passenger side 02 sensor...

Your o2 sensor is causing your misfires, I just had the same problem on the left bank of my car. Replace both front o2s and problem will be solved

I'd stop driving until you replace your o2s. Flashing ses means catalytic damaging misfires. O2s are $200 for both, cats are about 700 bucks

No problem, let me know how it goes for you. Quick question, does there car run fine for a couple of minutes then start stumbling from a cold start? You can also determine this is your problem if you have a code reader by clearing the codes while driving and seeing if your car drives smooth for a couple more minutes. This happens because when you clear the trucks computer it will run on factory fuel settings until your faulty o2s mess up your fuel trim again.

Yeah, at cold start it idles fine until it gets warmed up. I also have a code reader and when I clear the codes it seems to run ok for about a minute than the misfires again.

Hey Ad! That was it!!! Changed out the passenger side 02 sensor and now ses light is off, ran a scan with my ob II scanner and I got a green check! Runs perfect now! Well almost perfect, going to put a 2" lift on her and get a new front hd bumper. Thanks for your response. Oh if anyone is looking to get front oem bosch 02 sensors go to amazon, I got mine for $53 a piece with free shipping! Here's the link!
Amazon.com: Bosch 15175 Oxygen Sensor, OE Type Fitment: Automotive
