Hey everyone, I’ve got a P1151 code on my Ford Explorer, and it says there’s a rich condition on Bank 2. The car’s running a bit rough, and I’ve noticed my fuel efficiency has tanked recently. I’ve read that it might be related to a vacuum leak or a faulty oxygen sensor. Has anyone else dealt with this code? Should I be looking at the fuel injectors or MAF sensor too? I’m not sure where to start. Any advice on how to troubleshoot this? I don’t want to replace the O2 sensor if something else could be causing the problem.
