I had the heater problem on my Maxima, turns out it was the heater control valve that was getting stuck putting out cold air even when you adjust it back to hot with the slider bar on the controls. U can replace the valve for about 150$ or just manually adjust the valve under the hood and not mess with the slider bar control in the winter. Give it a try, it might work.

Thanks for your web-site! My 1990 Nissan Maxi ma keeps cutting off with me as I'm driving down the highway. First it starts sputtering, then the RP M's rev to about 4 RP M's, the engine light comes on, and it dies. It will start back up, but is difficult. It has been in the shop for going on three weeks now and they have not been able to correct the problem. They replaced the throttle, but then a few days later it was back to doing the same thing, AGAIN!! Help if anyone can!! I love my car!! It sounds like the fuel injectors as you said, but they've checked that and they are OK. However, they did not check the air intake temperature sensor, hopefully that will be it!

Fast Car, man. Good comments. I have had my 90 Max up to 110 and it was running as smooth as ever with much petal room!

GO MAX, a great car, but you must spend to maintain it, like any good car... expect it.

I bought my 1990 Maxima 5 years ago, now have 122,000 miles on it and it runs flawlessly.

Yes, of course the digital clock only works when I'm in a bad mood, and the power antenna stopped retracting last year, but, what an awesome car. I take a 700 mile trip every other weekend up the Columbia River Gorge to Eastern Oregon, and with a good set of Michelins, the only way to travel. Even on snow and ice!
