I've replaced the defective coil. My IS is now up and running!

To keep you posted: I've removed the air intake assy and unplugged the injectors one by ones: unplugging injector on cylinder 4 did nothing. So I swapped coil packs on cylinders 3 & 4 and the problem moved from cylinder 4 to cylinder 3. It looks like a dead coil pack. I'll oder one.

@ian Thanks for the link. But why would the ECU trigger that undocumented code instead of P0304 described in the Lexus diagnostic manual? @tigerfish Nothing done.

Thanks all for your replies. @ian I was not hoping an injectro fault :( were did you find the P031C definiton? @tigerfish I've reset once and it re-appeared, no other codes.

Hi all, I join this forum in desperate search of information... My beloved IS 200 worked like a charm for over ten year, and suddenly failed while idling in the traffic jam. The engine vibrates as if it were unbalanced. The check engine light is on. I've plugged an OBD2 reader and all I can get is a P031C code. I've searched the net and found nothing helpful. Nothing either in the IS200 Diagnostics manual from Lexus. Does anyone have a clue? BR Kela.
