look in your ouners manual,multiple things can be in one circuit with one fuse.

fit new shock absorbers

Your car is kind of new so I would be shocked if the shocks or struts or springs depending on the model are bad but you may want to check them. In regards to hearing the motor running in the back sounds like it is your fuel pump. hope this helps

two things Is the oil overfilled? Has the oil been changed recently enough? A fuel injector leak can put alot of gas in the oil. The valve covers may not be draining back to the crank case. The oil cap off just after its been running it shouldn't be full of oil. The oil stick may not be right, and the oil may need to be changed and only put in the right amount(5 quarts with the filter) and then run the car and then check the oil with the stick to see if the stick is right. I'm guessing that the oil smoke is coming out the tailpipe? Ifit's comingout from underthe hood then the motormounts may be broken enough to let the motor hit the belts to the engine bay side or the timing chain (worn out is grinding thoughthe timing chain cover and the oils coming out ( this usally takes alot of miles and many missed oil changes.

Check for fuel pressure and spark. Most mechanics do this in order to narrow down the problem.

This is actually done with a special glue which you can get from most Auto Parts stores or Walmart even. Before you re-install the strip your are going to want to remove it completely so you can clean the strip and the mounting area.

If you got it at the Auto Parts Store,you either got the wrong hose assy or you will need to get the dealers version ,because the after market doesn't always fit,when it comes to power steering hoses. About the only car partI have seen ,like that, in the last 40 years!

I would inspect the throttle cable first of all. They do have a braded cable which can break a strand and bind at areas inside the surrounding cable housing. It would be easiest to remove it from the throttle body and work it freely. That way you can tell if it binds up. Have some one push and pull up the gas pedal as well to inspect. You will know if this is the problem your having. Also lube the cable if you think it is still good to reuse

bondo and paint should fix this or take it to a bodyshop

Oxygen sensor just like they said.

Possibly heat shield or shield for the electrical connections.

Trouble Code Conditions:
DTC P0101-P0103, P0107, P0108, P0121-P0123, P0130-P0138, P0140, P0141, P0201-P0206, P0300, P0401-P0405, P0410, P0440-P0446, P0506, P0507, P1404 or P1441 not set, engine started, vehicle driven at less than 82 mph at 550-4000 rpm, BARO sensor over 70 kPa (10.1 psi), ECT sensor from 68-230ºF, IAT sensor from 64-158ºF, MAF sensor from 2.8-150 gm/s, MAP sensor from 16-105 kPa (2.6-15.2 psi), fuel level over 10%, and the PCM detected the Long Term fuel trim value was more than +20% for 6 seconds. The PCM controls the air/fuel metering system to good overall fuel economy, driveability, and emission control. During open loop, the PCM determines fuel delivery based on sensor signals, without the oxygen sensor input. During closed loop, the PCM adds oxygen sensor inputs to calculate Short and Long term fuel trim fuel delivery adjustments. Short Term fuel trim values change rapidly in response to changes in the oxygen sensor signals. Long Term fuel trim makes coarse adjustments in order to maintain an air/fuel ratio of 14.7:1.

Possible Causes:

• Air leaks in intake manifold, exhaust pipes or exhaust manifold
  
• Fuel control sensor is out of calibration (ECT, IAT or MAF)
  
• Low fuel pressure (fuel filter clogged, pressure regulator failure)
  
• One or more injectors restricted or pressure regulator has failed
  
• HO2S element is contaminated, deteriorated or has failed
  
• Vacuum hose is disconnected, broken, leaking or loose
  

Troubleshooting:2002 Buick Park Avenue, 3.8L, P0171

Probably going to have to replace the unit. I do not believe the lights are serviceable.

$75.00

have car scanned look at tps minnum should be around .50 at key on or running
also look at ect sensor if possible when ehgine is cold temp on engine should be within 5 degrees of outside temp
hope this helps.

check fuel pump open gas cap and turn on key to listen for whirling sound, if not check fuel pump relay, listen for clicking sound
