Mercury Repair Questions? Ask a Mechanic for Answers ASAP
Hello, my name is***** vehicle run rough at high rpm? Thanks.
Your still getting code 1041 even with hose clamped?
This usually means the catalytic converter is clogged, I'm surprised it runs fine at high rpm. Remove the front oxygen sensor and install pressure gauge. Pressure should not go over a few psi while reving engine, if so replace the catalytic converter. Let me know how it goes or if you have more questions, thanks.
