Multible Misfire / Misfire Cylinder 3 Gen 7

[cmw1983]

2001 Celica

Got 2 fault codes coming up

P0300 - Multible cylinder misfire

P0303 - Cylinder 3 misfire

I've tried swapping the plugs and coils over but it is still coming up as Cylinder 3 so don't think its either of those, Has anyone had anything similer or got any ideas what it can be or is likely to be

Much appriciated

Any luck with this 1?

I have just started getting a slight misfire - It comes in at 2200 RPM and you can feel a very slight vibration in the car.

Otherwise the car runs as it should with the correct power and the lift kicking in at 6200 RPM ?

Does this sound similiar
