IS200 Misfire on Cylinder 2

[natmann23]

Hello, I'm having an issues with my IS200 it is misfiring on cylinder 2 but takes about 20mins to develop.

It isn't the coil packs,
It isn't the spark plugs
Was recently serviced by someone else
It is saying "it's too lean"
Can't see any corrsion of wires or plugs

Any Common faults people know about or ideas to what I could check next ?

Cheers

Seen a few that have - lean airleaks.


Sadly I have seen one that was run with too larger plug gaps - this led to high EMF thru coil pack and the drivers became weak in the Denso ECU.

(this was never fixed due to the cost).

You would need to have a look on live data to see what's going on. Is it a definite miss on cyl 2 ?.
