Why did you make a second, identical thread?

Things to check:
vac leaks
burning oil? How much
How hot was your CAT when you went on the testing station?
Ignition wires condition?

HC usually points to Air fuel mixture and No points to EGR... typically. Be prepared to go down the rabbit hole of what ifs.

I couldn't find any posssible leak to be honest , and the cat, I ran the car before going but they had me waiting a long time and decide to turn off the car . Ignition wires were replaced about 4 months ago
