Hello, no pending code for bank one, only a lean code for bank 2? Is fuel pressure steady when it looses power? How many miles are on the engine? 4.0 SOHC?
Ok what is the maf reading at idle, is it still setting the code when you clear it?Can you look at live sensor data?
I mean do you have a scan tool that you can look at live sensor data when the problem occurs.
Ok, since fuel pressure is steady a loss of power on accel can be due to a few different things. So need to be able to look at mass air flow sensor, just because its clean doesnt mean its not working properly. Exhaust backpressure issue/base engine vacuum leak.Also need to monitor fuel trims both long and short term to see if only the right side bank of the engine is affected. Being a 4.0 sohc engine if the engine jumps time it can cause odd drivability issues
