My year 2000 3.2 litre V6 S Type was running sweet and then the other day on the way to work suddenly started running really rough over 2200 rpm. Also the engine shaped warning light would flash amber too. If I lowered the revs back to 2200 the engine ran smooth again and the light went out. I was away for 2 days (trucker and stay out sometimes) and when I got back I checked the levels and all was ok plus I had a look at the multitude of breathers and other pipes and they all seemed ok. Anyone else had this phenomenon? When I looked in my handbook it helpfully (NOT) said that this warning light is a malfunction indication lamp and I quote "This will only illuminate during the initial lamp check when the ignition is switched on." Sod all help there then. Any ideas?

Wrong forum (this is X-Type) but I can tell you flashing MIL = misfires so terrible they're causing cat conv damage. Do not drive it with that happening or you'll be replacing one or more cats

Read the codes.

Then head to the S-Type forum...
