2003 Eclipse GS

[killerclown1984]

Hey guys I'm looking for some help with my 2003 Eclipse GS. I'm getting a P0300 CEL random misfire. It seems to only misfire under a load. It runs fine in 1 and 2 gear. It seems to only misfire when I go over 3800 rpm if I stay below that it drives normal. It has 2.4l 5speed with 90,000 miles. I've replaced and gaped the plug, new wires, and replaced the valve cover gaskets.

Here is my freeze frame data
fuel sys 1 open loop
calculated load value 87.84%
engine coolant temp 181.40 F
short term fuel trim 0.00%
long term fuel trim 4.69%
engine rpm 4117 rpm
vehicle speed sensor 54.06
ignition timing advance 1 cylinder 22.00
intake air tempature 55.40 F
air flow rate mass air flow sensor 11.37 lb/min
absolute throttle position 100.00%

Any help will be appreciated. If I unplug the MAF sensor it runs fine.

If i unplug the maf sensor it run fine.

Bingo.

My 01 GT did the same thing when my MAF shit the bed. Got a new one and it's been running fine for 4ish years since.
