Misfire code on 05 MDX
2005 MDX runs rough, hunting idle. misfire codes on all banks plus random misfire code. evap monitor ready occasionally. what could this be? plugs replaced, EGR valve and passages cleaned.

Re: Misfire code on 05 MDX
What spark plugs are you using now and before the change. Use only OEM brand and specific heat range is the correct answer. Since you have the ability to monitor misfire, now once we have the correct spark plugs installed, you will want to monitor short and long term fuel trims, MAP voltage at idle and the O2 sensor voltages at idle and at a steady cruise.
Let us know what you find.

Re: Misfire code on 05 MDX
i am using the cheap autozone plugs. i shall replace them with OEM equivalent. i do not have any ability to check fuel maps nor read the voltages off the sensors. i simply have an ODB2 reader. i have heard these engines are very sensitive to the spark plugs.

Re: Misfire code on 05 MDX
How many miles on your MDX? Maybe it needs a valve adjustment. I have 95K on my 03 and also had cylinder misfire codes on all cylinders as well as rough idle until it is fully warmed (also swapped our the EGR valve thinking that was the problem) Dealer indicated that I need a valve adjustment and said it is not unusual that it will cause it to throw a code.
