First ever post for me here. I’ve been struggling to get my USA 97 16v running properly. The most obvious symptoms are poor mileage (18-21), very rich exhaust at idle, a code for bad catalytic converter, and an occasional misfire. The previous owner told me the catalytic converter was al busted up inside so he hammered it all out and it is now gutted. I Have been testing different things and it seems that the EGR doesn’t work properly. The EGR passes the stall test but when I rev the engine (with rear wheels turning) doesn’t seem to move the EGR diaphragm at all. After more research I learned that the EGR needs the CAT in place to function properly. So I have plans to reinstall a CAT but I am wondering if this could also be the source of my rich exhaust issue or is that being caused by something else? According to a scan tool all other sensors are reading fine. Also what would be a good option for a replacement CAT?
