Code P0306 - Cylinder #6 Misfire

[Bonjaz]

Anyone had a cylinder misfire happen?

Driving to work this morning, warmed car up and gave it a stab 2nd to 3rd and noticed MIL light flashing and car ran almost like it had dropped a cylinder. I pulled up it ran rough with light still flashing then light went out and car Idoled fine. Drove it the rest of the way to work fine.

When I got home I checked the error code P0306 which is cylinder 6 misfire. Anyone else get this before? Tomorro I will clear fault and do the basic checks and chang plug, coil and injector to a diff cylinder and see what happens.

I am suspecting valve springs but has anyone else seen one of these codes in an FG before?

Cheers guys

Cleared DTC faults, Changed plug and coil from cyl 6 to cyl 1 checked all plugs ect. Just went and gave it an absolute hiding all gears all rpm threw to limit and no fault.

Only thing I can think of is that little bit colder temps in the morning was enough to send valve springs over this limit? Faaaaarks me

I got this after reading the DTC codes with my XCAL3.  P0306 Cylinder 6 Misfire Detected.

 

Sounds similar circumstances, gave a bit when taking off and Engine light came on and car was idling rough.

 

I just cleared the DTC code today using my XCAL3 because I read on Internet that with OBD2 compliant cars merely disconnecting the battery may not clear the codes because they are stored somewhere possibly.  Not sure.  Anyways the MIL Check Engine Light didn't come back up.  But I did see a message P1000 OBD Systems Readiness Test Not Complete.  Hopefully that's not bad.

 

Here's what I found about P1000

 

Trouble code P1000 DTC is a manufacturer specific trouble code, most commonly used by Ford, Jaguar, and Mazda. It simply means that the engine control computer (ECC) has not completed its emission systems testing. A vehicle's engine computer must complete multiple self-tests known as Readiness Monitors.

What caused my vehicle to trigger a P1000 trouble code?

If the ECC has not been able to check all the monitors since the last time the vehicle's battery may have been disconnected or any repairs made which required clearing of trouble codes, the ECC may set a P1000 trouble code

How can I fix a P1000 problem and where should I start?

In order to clear a P1000 trouble code the vehicle must be driven through a Drive Cycle until all monitors are completed or in ready status.

Just drove around again and it was okay until I did a quick take off from the lights.  MIL engine light came on momentarily as engine idled roughly at next lights.  But it went out and drove okay after that.  Checked DTCs again and saw P0306 and P1000 codes.  Probably need to take it in for service after lockdown ends here.

don't worry about P1000, just worry about P0306 as that'll be a problem with either the cylinder itself or more likely a spark plug or ignition coil issue.
