What do you guys make of this info?
P0308 Cylinder #8 Misfire
P0307 Cylinder #7 Misfire
P0306 Cylinder #6 Misfire
P0304 Cylinder #4 Misfire
P0300 Random/Multiple Cylinder Misfire
A code P0300 may mean that one or more of the following has happened:
•Faulty camshaft position sensor
•Faulty catalytic converter(s)
•Faulty spark plugs or wires
•Faulty coil (pack)
•Faulty oxygen sensor(s)
•Faulty fuel injector(s)
•Burned exhaust valve
•Stuck/blocked EGR valve / passages
P0410 Secondary Air Injection System Malfunction
About 90% of the time that this code is set, the one-way check valves have worn out or failed and allow water (which occurs naturally in the exhaust) back into the pump. In any cold climate, especially in climates with higher humidity, this water may be more excessive. The water partially fills the AIR pump, it can then freeze. When the PCM commands the pump on, if the pump is frozen it cannot turn, thus overloading the circuit and "popping" the fuse.
Given you have multiple cylinders misfiring. I would be very suspect of the CPS
as it controls timing to fire the plugs, injectors and make it go varrroooom.
That would be my first suspect.
The p0410 is an issue but I don't think it would cause the random misfire.
This information is all available through search if you will begin to search. Then after searching and putting them in logical failure and asking for support on the problem might bring you better response.
1) You must have the codes
2) You must have organized the codes and inspected the engine
3) You should locate a manual to the engine to understand the components.
