engine just died

[BBR]

My Chmaera 4.0 HC has been running a bit rough lately so today I replaced the thermostat at bottom of swirl pot and fitted new plugs and leads. She started first time and sounded grrreat even on tickover she no longer sounded rough. So we went out for a ride. After about 5 miles, with the water temp
showing about 70 the engine just cut out, all the other electrics, eg lights, were fine.
Opened the bonnet, checked the plug and HT lead connections. (When I opened the bonnet I was surprised to see the exhaust where it comes up from pipes into 'Y' glowing red, is this normal?)Anyway after about ten minutes she started but was very rough, I just about managed to limp the two miles home.
Any suggestions as to whats wrong?
As ever all suggestions greatly appreciated.

mine did this once, and i was told it was fuel in the exhaust. mine had been sat for about 10 mins with the ignition on, but not the engine running. cleared itself and never happened since, though i now never leave the ignition on unless engine is running.


not sure it helps, but the same as mine.
check the manifold though as the heat can cause cracks now

mine did that i changed everthing after manifolds glowing looked like they were melting ,lambder sensers, leads stepper motor ,it was the plugs in the end new set ran fine its trial and error ive found

As suggested you have a misfire on that side of the engine, the glowing was the precats getting a bit hot

Most likely you have disturbed a HT lead or something, you can check which pot is misfiring by touching the end of a cable tie* onto the manifold for each cylinder, it'll melt if the cylinder is firing, trial and error - misfire found....

'* or a drops of water, WD40 etc

Trial and error is a very expensive way to solve problems like this and can lead to more damage along the way - melted cats, for example. If you've got a misfire and don't know how to fix it yourself, I suggest you get it to an expert as soon as possible. As well as potentially damaging the exhaust, you can easily cause heat damage to other components in the engine bay and may even have a fire hazard.
