Hello all
I’m new to this website. I have A 97 Maxima GLE. 117,000 miles on it. It’s my Finance’s.She bought it in 2000. The check engine light just came on. The codes are telling me that it’s the EGR valve, O2 sensors Bank 1 and 2 and the knock sensor. Is there one of these issues tripping the computer to read all of these. I have no problem replacing any sensor but I don’t want to replace one to find out it wasn’t the one tripping off the computer. Her ex supposedly took care of this car but I replaced the air cleaner and it was so damn dirty I Can’t see this to be true. Yesterday I replaced the plugs with NGK platinums and replaced the PCV valve. My girl always ran 87 Octane thru it. I have been reading threads saying this is not good. Someone has told me to start with the 02 sensors first. Do you guys/Gals agree? So far in the last 2 years I replaced- New Starter, Alternator, belts, axles, battery, plugs and pcv valve. I don’t mind fixing this car up. It’s a Great looking car. I just want to fix what needs fixing not wasting my money guessing.
Also the exhaust is banging around the bottom on the Car. I'm going to have this replaced. Do you recommend a muffler or do I go with the stock shop muffler? This car is just used as a regular everyday car.

Hi people
I replaced the plugs and the pvc valve, reset the computer . I drove the car for a week then the check engine light came back on. Except now, I only have two codes, EGR valve and Knock sensor. I just ordered a knock sensor for $122 it's a standard. I read that these cars just go thought theses sensors and if I replace it, I will eventually notice an increase in performance once the computer learns to advance the timing. Well, no one gave me any type of help so I will keep posting just in case someone else is in the same situation. The plugs were NGK platinums. like 2.98 a piece. The two O2 sensor codes are gone. Two down ,two to go. I plan on installing the new knock sensor and cleaning the EGR Valve. I'll keep everyone up to speed.

One more trick since we are all getting raped across the coals on gas. Here is an easy way to make sure your favorite gas station is pumping out the right gallons per Dollar. I have heard of gas stations prices vs. gallons being off. I'm from Philly but this happened in GA. Easy math. When filling up at what ever price per Gallon... Let’s say in Philly it’s 3.85 a gallon as your filling, stop at 10 Gallons for a second, check the price. The price should be $38.5 $3.85 a gallon X 10, if it's more then 10 X per gallon then your Station's pumps are off. Whether it's on purpose or not, you decide but this is a way as your filling up to make sure the gas station and the price all coincide.
