Name is Greg, My goal is to provide you with excellent service – if you feel you have gotten anything less, please reply back,

Hi .

You have to get your car hooked up to a diagnostic scan tool to check for malfunction codes .
The exhaust sensor is what is glowing looks like you have a damaged catalytic converter, this is what is making the engine run ruff.

When the light starts to flash this is a misfire code and when it stays on this means the management system has stored malfunction
codes , from the codes you will know what has malfunctioned .
You have to get this checked as soon as you can before you have a bigger issue with the engine and exhaust system.

If you need further help with this issue or the codes you get from the management system then please get back to me .

My goal is to provide you with excellent service – if you feel you have gotten anything less, please reply back with the reply box below and not the poor or bad service button ,
For further assistance there is no extra charge after accepting.

I have now replaced all the coils plugs ht leads and exhaust sensors and this seems to have cured it thsnks.

Hi .

Thank you for getting back .

After having a bad misfire and one of the sensors glow have them checked
with a scan tool and check after a few days for malfunction codes
as said a bad misfiring engine MAY damage the Catalytic converter.

Replacing the O2 sensors was a good move these will let you know if the Cats where damaged .

Kind regards Greg
