Faults:

My car stalls after the engine has heated up to the normal driving temperature.

I went to the Nissan dealership in my city. They ran a check on the car's computer and told me it was the O2 sensor on bank 1.

Paid them to replace the sensor. The problem did not go away. Then they told my idling motor may be out. It will cost me $600 for the part, and additional charges for how long it will take them to fix it plus tax. My estimate right there was heading towards $1000+.

I decided to do some research on my own, and found a comment posted by one guy from Canada - I did as he said, and my car is wonderful... see below.

General Comments:

The Nissan Maxima is great car. If you review the owner's manual, they recommend that the mass air flow meter should be changed at 40000 miles. That is the main issue with this car. Also the air filter must be replaced at any time it is dirty; do not clean it and re-use. Just replace it when it is dirty, period.

Nissan has so many sensors on the car, however the sensor that controls air intake is the most critical for smooth performance of the car, and that is the mass air flow meter. It is one of the things listed in the owners manual DIY, including starter plug.

Got a DTC code p1320 for coils. Replaced all six coils. Still had a problem. Went to Nissan and had a diagnostic done for 100.00 cdn. They said the MAF sensor had failed.

Managed to get all six coils for $550.00 Canadian including tax.

MAF sensor I got for $530.00 at a local Toronto Nissan dealer.

I installed the new MAF sensor and air filter. All 222 ponies are back at the gate and ready any time I hit that pedal!!!

I forgot how much power this car really has!!

Woo hoo.

I too have had to replace all 6 coils at a cost of $1200 at the dealership. They were not able to determine which one was bad and pressed me to have all of them replaced. The car is paid off and I only have 70,000.00 miles on it, and I did not expect to have to pay for such a costly repair at this interval. I have read over a hundred complaints about this coil problem, and am very disappointed that this is occurring at such frequency. I take very good car of my car and have it serviced often for routine maintenance, but after reading about the hundreds of others who have experienced the same problem, I will not be purchasing another Nissan again. I urge others to complain to Nissan, and sign the petition on line.

General Comments:

The car is enjoyable to drive, but expensive to maintain. I think I have even replaced an O-2 sensor more than once.
