Sometimes wnt start unless i give er a lil gas. And its getin were its doin the sputtering everytime but once i get it to going good it stops and gains power again

I have a 2002 Buick Century Limited edition and the gas gage has been going crazy. If I sit for a minute on a hill it reads no gas and then the dinging goes off to tell me that I have no gas....But if I fill it all the way up its fine....Until it gets to about 3/4 of a tank then that's when it goes crazy....I never really know how much gas I have do to this....Please help....Its been doing this for a while now....Thank you.....Jennifer

got fluid, sometimes it works fine, sometimes it shakes in high gear

Climate controls seem to be operating fine. When the problem 1st began, it went back to blowing cool 2 days later w/o any repairs.

Replaced electric fan motor, radiator is circulating good, water pump not leaking.

Service engine light on and went off on own prior to coil and filter can I unclog cat? Told replace

Now I can see everything on the odometer just can't see the miles on it nor when I I put it in park,drive, reverse, neutral. So what could be the problem

The only issue I am having is: it's dripping oil when parked. The oil drippings are fairly small. ( about the size of a QUARTER). I had Intake Manifold replaced by friend of a friend in DEC. of 2012. Any input is greatly appreciated. Thank you,

P.S. BTW Mechanic is not yet Certified. Attending Mechanic school this month. He does have experience thou..

later went to start it and started right up. there is little lag in the starting but has started each time. this happened about a week ago. worried if it is the starter, ignition switch or gear range finder in tranny.

after replacing both & i past the emission part oif the smog but the check engine light still reads o2 sensor

05 Century has over 227K miles. Have the oil changed regularly, been running full synthetic for over a year. 7 months ago replaced the thermostat, only knew it was stuck open because it failed emissions test. Problem #1 A few weeks ago it suddenly smelled of burning antifreeze. I drive about 500 miles a week some heavy traffic through Boston area, car does not overheat, AC worked last summer but not now. Heat seems to work fine, defroster is not working as well as it used to. The stench inside the car is awful, can't smell it outside. Not sure if it's relevant, but there is a glob of dried orange gunk where the water pump connects to the head. (car takes dex cool) it's been there for a very long time and doesn't get bigger.

Problem #2
Car started clacking at low speeds front right wheel area. Nothing looks broken or damaged except the upper strut mounts are severely corroded due to horrible winters here. I watched a video of a car being driven with a bad strut mount/bearings and it sounded exactly like mine. Almost like a trotting horse, and stops at around 25-30 mph. Can't feel it in the steering wheel and seems to corner fine. I have had cars with issues with a control arm, broken sway bar, and worn tie rods and this doesn't feel or sound like those did.
I'm just hoping someone can give me an idea if my suspicions are correct. I'm a single female and tend to get the runaround, even at reputable shops. My son and nephew who are back yard mechanics are planning to do the repairs.
Thanks!
