Just bought a '98 1.5. The test drive was good, no problems and no light. The next day the lot boy washed it before I picked it up and he hosed the engine. When I started it it ran on three cylinders and set a code for #1 cylinder misfiring. I replaced the cap, rotor, wires, and plugs after I dried the water out of the plug hole. I pulled the air cleaner top off to gain access to the car and rotor. Forgot to tighten the clamp on the hose to the throttle body. It ran fine that day. The next day it still ran fine but the CIL started flashing on the drive home. I had read the owners manual and it said to get it checked soon, not that I needed to shut it off so I drove it on home(6 miles). Now I get a P0421 code after driving about 10 minutes. The scan tool says that the warmup catalyst is below its threshold for the current operating conditions.
Question 1: Did I kill the cat by not stopping immediately?
Question 2: Is there a way to test the cat or do I just replace it?
Question 3: Is there an aftermarket cat that fits without a lot of trouble or should
I just buy it from the dealer and avoid all the issues of making a
"universal" one fit?
Not fixing it is not an option so please don't waste time by suggestting that.
Thanks
