check to make sure #5 spark plug wire isn't bad,make sure you have not wired it wrong from changing plugs. You should purchase a chilton manual if you haven't already

check your wire harness on the top of the engine. Volvo must have bought harnesses from Mercedes. The insulation just cracks and disintegrates, then the wires short. Not good for an ignition system.Once they short It can fry the circuit for that cylinder in the computer. Does not set a code other than Misfire.

Weell it sounds like you have the days old problem Pepole dont know how to look after there cars.
The muck you still have in the engine isent doing it any good and so you have to get rid of it all, as its in the engine block and is got to go ,,so drain a little of water out and put in 1/2 a cup of washing up liquid in the radiator and start the engine and let it get hot and take the reves up to 1000 rpm now and then to keep the water going around the system, after about 1/4 hr turn off,,stand for 10 minutes ,,and then remove the cap slowly and then take off the Bottom hose and let all water out also take off Top hose at the engine end and put the house water hose in the top and turn it on till all water comes out clean. Then put hose up into the bottom hose and do the same again ,and the same in top again.Now with a clean engine you can do the same to the new Radiator and wash out all gunk .then check the thermostat and make sure its 100% (any doubt through it out) and take note how it comes out so you can fit a new one the same way,
Now refit both hoses and fill with coolant or antifreeze and TURN on the heater to hot before starting as you also have to get out the air from heater when it was drained and you will trap the air which might cause you code problems..
But now try service light reset
1,,Turn Ignition to Number 1position.
2,,Press and hold "day counter"reset button and turn
ignition to II(second) position,hold down for about 12 seconds.
3,,Afterservice light flashes,release button,there should be 2 beeps confirming reset was successful.
Let me know how you get on .. Ron

SOURCE: misfire on number 6. changed

What vehicle?

Spark plugs never misfire, by design, Wear yes,that stresses the
ignition modules

If you have a coil, that is for all cylinders,the others fire okey !

We need your year,engine, V6, V8, etc, to help

You never change parts to solve any issue
That is called wishing,hoping,pushing,poking,

What code # did you get PO306?

2000 Volvo s80 t6 engine will not start.


I'm too familiar with the T6 engine, but I *think* the T6 engine has the CVVT solenoid right by the exhaust cam and they are known to get weird and you need to clean it.
I believe Volvo has a gasket with a screen in it to keep it clean.

The cam sensors are pretty sturdy and rarely fail, so I'd check that last.

Did this happen right after a timing belt change? If so, I'd double and triple check that you got everything lined up exactly right. My process is usually to use white-out to mark the old belt and gears and then transfer the marks to the new belt and if all marks still line up when it's back together I am good (and yes, it's been good this far hehe).

If it's the CVVT sensor, buy a new gasket, remove the sensor, soak it in carb cleaner and give it a "work-out" with 12 volts if you have a battery charger or whatnot. It's possibly a fresh 9v battery might work too.

If you got any other codes, even if you don't think they're related, they might be.

I wouldn't touch any other systems if the car would run before and now won't, and all you touched is the cam timing and that's the code you got. Fix that first, THEN if you have other issues, you can tackle them.

Volvo s80 t6 after putting my serpintine belt back on when i started the car a good size of the belt ripped of and wrapped around my harmonic balncer to the timming belt and shut my car right down


Did the piece of serpentine belt actually make contact with the timing belt ? The timing belt should have been behind the timing cover.
And does the engine crank normally ? Normal compression ?

2003 Jaguar X Type has p1314,p0300,p1313,,p0303,p0301,p0302,p0305


the fault codes you have are all misfire codes p1313 and p1314 are manufactuer codes only. but they all point to same issue check the engine wiring harness under the air box for chaffing also the on plug coils are very unreliable the spark plug internal resistance is critical use only genuine plugs we had to change all 6 because pattern plugs had been fitted and check for water ingress in to the ecm/connector that may be the problem
