Hi,
I just replaced the spark plugs recently including the wires but I still get the following codes.
p0300 random / multiple misfire detected
p0303 cylinder 3 misfire detected
p0401 EGR flow insufficient
p1133 manfacurer control
. fuel air metering
p0401 EGR Flow Insufficient
What would be the solution to this ? Thaks

It is possible your ECU is damaged, and isn't activating the spark plugs at the correct time. Or, it is possible the ECU is still activating spark at the right time, but is monitoring itself incorrectly and reporting an error.
It sounds like an electrical problem, in any case.

Check your intake manifold gasket for leaks.
