need some help diagnosing my problem. I was driving on the 401E yesterday and all of a sudden I wasn't able to go any faster than 120 km/hr. The tachometer maxed out at around 4000 rpm and any gas given to it after that point I would feel a loss of power and the engine would sound like it'd be doing 7-8k rpm. I pulled over to the side of the street after taking the first exit and I could hear rattling and as if there were little pieces flying around inside the exhaust system as I was revving the engine in neutral.
I'm thinking most likely its my catalytic converter dying out on me as my mechanic had told me before that the honeycomb inside was probably disintegrating. As a temporary solution do you think it'd be a good idea to find a mechanic to gut the cat just so I can drive back to Toronto and put on a new exhaust system?
Would it be possible that the cat is clogged and creating back pressure in the exhaust system causing it to lose power at 4000 rpm? The check engine light turned on shortly after this but I have not checked the codes yet. I have replaced my spark plugs and distributor less than a year ago. I'm 430 km away from Toronto so any help or input would be much appreciated!
