I've swapped coils/plugs quickly and didn't make any difference. Hoping and praying it's just something simple like damaged wiring and not a dead cylinder with low/no compression. I'm on 260k miles, so anything is possible.

ommony - sadly yes finally got a confirmed diagnosis. - Burnt valve, who knows the cause, but its head off and rebuild. Options were second hand engine (unknown beast) or scrap the car, it's 2007 SE Sport, but I love it and have done quite a bit to it, this is the first engine issue. I figure I can strip out the head myself, (a special Cam tool set required but readily available -£100), plus about £800 for a complete back to new head rebuild by a very helpful chap in Par Cornwall, I'm in London, but my brother lives near by. the gasket set is about another £150 plus consumables, the garage wanted £2.5k +, defo not in my budget. Since these 3.2's are getting rarer I think I'm going to do this and keep it.
I have two general questions for anyone who has an opinion.
1. Should I replace the timing chain & tensioners whilst I'm in there, &..
2. If I'm replacing the chain is it wise to replace the sprockets(Both cams inc. VVT and lower smaller drive unit sprocket (very expensive option!! about £800 extra for a full chain and sprocket set!!!).
3. Does anyone have any good recommendations for gasket sets for this little job!! & or Timing chains, Although I'd probably go original fro that if I change it.
Any comments welcome thank you.
