What diags are you using ?


Have you considered the ECU could be at fault.

Are the Lambda sensors ok?

Are the cats blocked? Or did they rattle? Punch one and see if it rattles.

Have you swapped the leads aro=ound to see if the misfire moves with the lead?

Are the plugs good?

Hi delboy - I had a similar problem with arcing/tracking in a distributor cap (SL500). Signs inside the cap are not hugely obvious, but are seen if inspected closely.

Worth a look, but if this is not relevant to your ignition system, please ignore.

Some indie told him that the throttle bodies were US £1.5k to repair. Needless to say hes getting rid of it.
