I have a zafira 1.8 that was diagnosed with a duff cat.
I have changed it out and it has made a big difference but not perfect.
I have connected my elm scan and get
air intake temp: 71c
Cat temp 300 at idle but shifts to 600-700 and 1200 I floor it.
coolant reported at 95c
long term fuel at 99.967%
short term varies between 91-98%
O2 sensor voltages between 0.3 and 0.8
The engine feels real hot and the coolant was bubbling in the expansion bottle.
Is this normal??
