2001 Pathfinder Codes:p1320 and p0171
Hello, I have been getting codes p1320 and p0171. Engine was misfiring often. I read hundreds of posts relating to these 2 codes and finally dished out the big $$ replaced all 6 coils, all plugs and air filter. Got MAF sensor cleaner and cleaned MAF. Still the car SES light keeps coming back on after clearing the code. After doing all the work the car has a very rough idle but no crazy shakes like when it misfires. Gas millage is in the toilet, I barely drive 60 miles per day and it seems like it almost takes a quarter tank of gas. I am at a total loss on what to do. Any advise? Thank you.
