02 Nissan Altima-HELP!!!!?

Question

I've never had problems with it before, but it now has about 85000 miles on it, so it's probably starting to wear, but now I have multiple issues:

1. When I start the car, not always, but sometimes it kind of rumbles and shakes, then stops after a few seconds.

2. When I drive, I can hear the front left tire as it rotates. it's almost as if there is an uneven spot in it or something. It started when I took my car in for a tune-up a few months ago. They balanced, rotated, & aligned the wheels. I called them and they said the tires were just settling to their new position, and it would go away, but it hasn't.

3. The temp. gague has started going from normal to hot, but it is constantly moving. It's changing faster and more drastically than the car temp can physically change, so I think the temp. sensor thing might be broken? I'm in FL, so I can't tell if the car's actually oddly hot or if it's just the sun.

I just had my spark plugs, oil, brake pads and rotors all changed.

I'm having my thermostat changed tonight, so I hope that problem will go away.
Please provide as many details as possible. I would feel better if I had a better idea of all the possibilities and what causes these issues and what's going on in there too make this stuff happen. Thanks!

Answer 1

rotate you're tires back and don't rotate them again "ever" i don't rotate tires on my cars each wheel has a unique ware pattern when you rotate them they need to ware to the new ware pattern this will some times cause a weird ware pattern that will give you a hop or vibration

replace them when warn out or if the shaking gets worse

get you're timing belt (if it has one some of those have a chain) and thermostat changed your anti freeze may be low replace the radiator cap (for maintenance)

as far as starting you may have a valve lifter that leaks down not much you can do on that one or a valve seal does it smoke a little out the tail pipe when you first start it up

Answer 2

so which you drove this automobile the mandatory one hundred,000 miles so which you necessary spark plugs. particular the plugs are frequently threads and that they stick into the combustion chamber authentic into the midsection. the place they might ignite gasoline and air. final week I bumped off a series from a Altima with 147,000 miles I replaced a defective air flow meter on that automobile. some circumstances the radator cap rubber swells up and blows the gead gasket then the plugs grow to be corroded from interior and harm off not finally end up.. The QR 25 engine is large till it gets overheated or cat converter breaks up and sends junk into the engine.
