Glowing Exhaust
Discussion
Can anyone shed any light on this little problem,
The other day the Chimaera was running like a right dog, as if it was on 4 cylinders, nursed it home, about a couple of miles, popped the bonnet and the large dustbin bit of the exhuast manafold was glowing bright orange
The next day it ran as normal, but then decided to cut out on route to the pub,
conveniently just next to a layby 
started straight away and carried on about 100 yards cut out again and coasted in to pub car park.
Got home fine, and went out today and B@$t@rd Car ran like a dream
Anyone got any ideas whats up with it?

Anyone got any ideas whats up with it?Seem to recall from a thread about a year ago that a glowing manifold is caused by unburnt fuel igniting in the exhaust. If this is the case then I would assume that you are looking at something electrical and that the mis fire was putting loads of fuel through to the exhaust.
No much of a clue I know but get it sorted quick or your cat will die.

adamb is correct when the car is misfiring (prob. electrical) unburnt fuel blows out into the (very hot) manifold and ignites. Did you notice a godawful noise while it was running rough ? This comes from the sudden increase in pressure in the manifold.
The car cutting out adds credence to an electrical fault be the cause-when our Dino started to do this it was just the HT leads (unfortunately we found this out after it'd burnt the paint off half the back of the car and trashed the exhaust ££££££££££££££
). Given that it's so soggy atm it might be worth doing time honoured things like spraying WD40 over the connectors and tightening up everything electrical ?
Unfortunately this may well have led to a poisoned pussy-they don't take kindly to a dowsing in unburnt fuel. You could get this checked now if it's a new car as it's a warranty issue (lol) or just wait until the Mot. A dead cat won't do the car any harm it'll just increase your emissions markedly.

Ref the running problem I would suspect you have a faulty Lamda probe or the wiring/connector to the same. Also if you run a cat equipped car with a mis-fire the unburnt fuel congregates in the cat making it glow bright orange or melting it completely. This is why it says not to run the car with a mis-fire. It can be checked out easily with a piece of diagnostic kit called a PDL. This can tell if the Lamdas' are reading correctly etc. Don't keep running it get it checked out.
