What kind of damage would happen to my car if I keep driving it with those bushings damaged

Checked for Intake air leaks - None
Replaced front heated oxygen sensor
Cleaned fuel injectors
Checked for Exhaust gas leaks - none
Checked fuel pressure - good
Cleaned Mass Air Flow (MAF) sensor
Checked Positive Crankcase Ventilation (PCV) hose connection - no leaks
I am at a loss for what to do next. Any advice would be greatly appreciated.

My car has about 125,000 miles on it and it has started running a little rough and is burning quite a bit of oil. I am going to get a tune up but don't want to be taken advantage of by the mechanic...I would like to know what exactly a tune up consists of for this model. Also, what could cause a lot of oil to burn?...I see no puddle under the car and haven't found a leak.

brakes started going to the floor bleed them worked for a few miles went out again

RPMs has to be 3,000 for heater to blow hot air. When RPMs drop the air cools off. ??

need to be able to diconnect it in order to replace it

battry replaced at walmart, with in 5 miles, motor runs rough, oil light blinks on and transmission shifts only at high rpms. stopped and checked oil, called walmart and guy said it needed oil change. went home, 20 miles. oil light on and check engine light on. next day, start it up and no warning lights on, drive 20 miles, no lights on. stop and shop 1 hour, car runnin ok, within 5 miles, warning lightss on and same problems. 1 week later, same thing, 20 miles, ok shop, start fir home and lights come on and now motor is knocking, bad. what happined?

where is the heating control valve located on the 2001 toyota celica...how is it controled...by vaccuum or mechanically???

The heater will not heat while running around in town but if out on the highway it will heat...does it have a heater control valve .... does the water run through the heating coil all the time???

The heater doesn't always work. Sometimes it will come on after driving for a while. I have checked the water level and the leaving water line out of the heater is cold. What could it be?

Approx cost to replace possibly the cable affiliated with the clutch? clutch has been replace 3-5 months ago. driving this morning heard a pop when shifting gears into 3rd now stuck in 3rd gear. cars runs fine but stuck.

how do i get the driver side window back on its track to be able to role it up?

ok so this is my gfs car and i havent got into it to see whats up. but from what she says it had a stuck valve and she got it fixed but a few days after, it started burning 2 quarts of oil every few days. whats wrong with it?

So i know that when a charcoal canister goes bad it can effect the catalytic converter. But I was wondering if anyone knew how long roughly it could take to do that?
