1992 Nissan Maxima GXE review from North America

I am driving a 1992 Nissan Maxima GXE 190 horsepower and 190 pounds feet of torque v6 SOHC. This car is super fast. The car has 120,000 miles on it I just got the fuel filter change, spark plugs. Now I just need to by some spark plug wires. Because it is doing a little missing and jerking when I take off. I took the car back to where I brought it from and they replaced the bad wire until I can buy some brand new ones. I am thing about replaces my PVC value sometimes this week. On January 29, 2005 I went to Wal-Mart and got a oil change and they said I need to replace my CV Boots and get the little oil lean fix they said it could be a seal or gasket needed to be replaced. So, I contact some auto repair shops and told them when I turn right and left it makes a clicking sound and they say it’s the CV Axel.

Here are some questions I need to be answer ASAP if they can be.

I filled my car to ¾ of a tank and set the trip to 000 and measured how many miles I can go from ¾ to ½ I went 116 miles. Also from ½ to ¼ I got about 71 miles. Driving from ¾ to ¼ I can go around 187 miles and they does not sound right to me. So my question is. What is the problem? So is that a good or bad thing if good or bad please explain what I should do.

I was driving on I540 in Arkansas at 90 miles per hour and my rpm was at 3,000. I was just wondering if it is correct for going 90mph and your at 3,000 rpm. The transmission is great it changes gears better than any car I have had. I just think the speedometer is not working properly. The people who I brought the car from they had just fixed the speedometer. I just want to know if I am driving the right speed limit before I get stop.

What is the best sound system I should put in the car. Should has: Cd player, front and 6x9 speakers as I mean best sound for less money.

My power locks are not working. What should the problem be?

I have a lot of break dust on my front wheels. The car is stopping great and they are not making any noise. What should I do?

How much does it cost to replace the outside temperature sensor?

How often do you all replace the belts? When can you tell if you need to replace the belts?

So, please answer these question if you all can.

THANKS,
