My 01 MDX recently started hesitating very badly. It starts fine but as soon as I hit the road when I give it gas it hesitates and I give it more gas and it gets going but when I reach cruising speed it starts hesitating again. Today I punched it and I got a engine code and the VTM light lit up. It idles erratically when in park also. The weird thing is it doesn’t do this all the time. Yesterday it was fine, today it’s hesitating badly. The VTM light went out when I restarted the car and engine code I got was P0132, O2 sensor reading high! I can’t imagine why a bad O2 sensor would make it run like this but? I’d appreciate any help as I don’t have the money to take to a dealer if I don’t have to. Thanks in advance. Billyzack
