Hi there everyone!

I am working on a 2005 XG350 L, is has a P0300-(P0301 thru P0306 as well) Tachometer is also Inoperative when this occurs. Performs perfect after the car begins to warm up.

The freeze frame data was at 80f temperature @1,113rpm and no m.p.h. when triggered, only at cold temp as it is warming up.

Does anyone have a diagnostic chart they can email me or send me a hyperlink?

I may have suspicion that it could be 1 of 2 things, like the Ignition misfire sensor or ignition coil module.

I do not like to just start replacing part and not fixing cars, so this would be of great help.

Thank you-

 

If it throws 'multiple misfire' (300) and one for each cylinder (301-306) I'd very much suspect the misfire sensor rather than the coil(s). Quite unlikely all 3 will go the same moment.

B.t.w. why a poll ?
