Hi all,
My levin has failed NCT on emissions,

Ive read about high CO and says it could be a map sensor, TPS sensor
Wouldnt these throw up an error if not working?

It sometimes back fires too,
Would a new Cat sort it out if theres no engine errors flashing?

Any help greatly appreciated guys.

Possibly a new cat and check for leaks in the exhaust system. A leak in the system would throw off the readings.

Check your cat mate. Also, give it a good run before going back to check it
