Everyone with random misfire codes!!!read me!!
Hey peeps I was doing some research because I have checked everything and my car is still misfiring in lower gears during hard accelerating. I ran across this! hope it helps. http://ww2.justanswer.com/uploads/th...01_misfire.pdf
Very interesting....
When owners of ’00–03 3.2TLs, ’01–03 3.2CLs, and
’01–02 MDXs complain about the engine running
rough between 40 and 70 mph, are you finding
misfire DTCs (P0301 thru P0306, P1399, P0133)
set? The problem could be clogged EGR ports or
an upside-down intake manifold upper cover
gasket. Since the EGR ports aren’t symmetrical, an
upside-down gasket covers some of the ports,
creating uneven EGR distribution.

Dreaded P0301 -P0306...
Hey, I recently had the multiple mis-fire codes and read all the posts. I tried to get technical and take a resistance readings from each of the ignition coils. They all checked about the same... Next, while the car was running I disconnected each coil one at a time and found the bad one; there was no change in the engine when I disconnected that one, all others the idle changed. Of course it was I believe #1, the hardest one to get to (back passenger side). I purchased a new one and replace the suspected bad one and $44 later, reset the computer, all is well. Thanks to all the posts, you saved me $$$ Have a great New Year.
