Hello all,
My friend recently picked up a 2004 Acura MDX with about 186k on the clock.
Got the car and it wouldn't drive above 65ish without misfiring. Took the intake apart cleaned the EGR ports since they were clogged with carbon, replaced EGR Valve and replaced all the spark plugs since they were fouled up. Car has been running fine since, but just yesterday it misfires on a cold startup then runs fine. After it warms up the rough idle is gone and it only seemed to misfire on startup. Codes on the vehicle were P0300, P0301, P0302, P0303, P0304, P0305, P0306.
Any ideas what this could be? As far as I know the 2004 models don't have the idle air control valve.
Any help is appreciated trying to get this issue rectified.
