P0300, P0301, P0302, P0303 and P0306 only

Hi,

My wj 4.7 shown the codes P0300, P0301, P0302, P0303 and P0306 only. Every time i clear the codes, it runs fine and after a while, mil flashes, and lights. Searching for the errors, P0300, P0301, P0302, P0303 and P0306 shows up.

304, 305, 307 and 308 does not shows.

What could be the cause for it?

Any help is welcome.

Best regards,

Paulo

Boa noite Paulo.
The codes you have are for multiple misfire (P0300) and misfires for respective cylinders (P030X).
Now it is important to know if the engine really misfires, or that it is only throwing those codes. When it really misfires, the engine will run rough.
