2007 q7 4.2 8 cylinder missfire
I get a flashing cel when I accelerate hard. The codes say misfire in all 8 cylinders and random misfire detected.
so far I have replaced the in-tank fuel pump, in-tank fuel filter, an intake actuator, spark plugs, and ignition coils.
I have also just cleaned the carbon off of the valves and replaced the intake gaskets.
The last thing I did was check the compression, all the cylinders were between 175 and 180.
Any ideas?
