  • 1999 MERCURY COUGAR
I have a 1999 Mercury cougar with 81000 miles, I recently pulled up three trouble codes on it - P0420 catalyst efficency below threshold (bank 1) P0430 is the second code and it says the same thing but it's for (bank 2) I pulled out both o2 sensors and gave them a good cleaning, i'm still not sure if that was the problem and what it means bank 1 and 2. The last code I pulled up which I think is the main problem is P1519 IMRC (intake manifold runner control) stuck closed. I have a chilton book and I cannot find where the IMRC is located on my 99'. I was wondering if you could help me with this last code and is it the cause of the other two codes? Thanks
