Nissan Repair Questions? Ask a Mechanic for Answers ASAP
Hello my name is ***** ***** thank you for your question.
This type of question could be tricky to determine with out using a scanner to monitor some sensor operations and the use of a fuel pressure gauge.
First thing I would check is the brand spark plugs. These engines are sensitive to the brand spark plugs I would make sure it has NGK platinum plugs. Then I would clean and service the throttle chamber. I would also check to see if the car has a after market fuel filter. If it does, I would put a OEM fuel filter in the car. After Market fuel filters can restrict fuel flow.
So lets check those things to start and let me know what you find.
What is the fuel pressure? Also did you clean the throttle chamber?
The rear 02 reading is correct, and the front 02's sound right.
Do you have a check engine light on when the car is running?
What is the exact code you are getting?
That code is for the Bank 2 front 02 sensor. Did you try clearing this code and see if returns?
I do know that the 96 Maxima's did have some harness issues where it bends behind the passenger strut tower area. So try to wiggle the harness while someone helps to try to start the car when it doesn't want to start or when it takes a while and see if it starts and let me know
This sounds like it may get to involved to handle Online. 96 Maxima's are known to have harness issues as I stated. So I will have to opt out and re-open this question back up to see if any other experts have any info to help you.
