Remove the plastic shroud which covers the engine. This can easily be done by unscrewing the oil fill spout (the 3-inch extension onto which the oil filler cap fits) by unscrewing it a half turn and lifting it out. This exposes the fuel injector body and mechanism.

Remove the rubber boot between the air box and the fuel injector body, then locate the "screen" which covers the intake. The screen should be held on by a "C" shaped ring, remove this then work the screen out. It's a little tricky to get out but it's not impossible. Spray some WD-40 (or other lubricant) on the butterfly shaft bushings and this should fix your problem.

2001 Buick Lesabre starts normal everyday. Car sits three days or more will not start unless you put the accelerator pedal down at least twice

put the accelerator pedal down at least twice ? While cranking the engine ? key on ? what ? Your vehicle has electronic fuel injection ,not a carburator . Pushing the gas pedal doesn't do anything The only thing if pushing the gas pedal to the foor an holding it there will put it into clear flood mode , shutting off the fuel injectors .

I have a 2002 buick lesabre gas smell inside the car they said its the map sensor

Ok, Is there a question?
Usually with gas smell, I look for external gas leak? If I find nothing, I check the evap system. Next, I check if the vehicle is running rich or lean? Were there any applicable trouble codes? If so, what were the codes? The map sensor could have a problem?

Throttle revs by its self without using gas pedal, car will keep increasing speed have to control with

Could be two issues. First could be the cruise control. I would try disconnecting the link to the throttle from the cruise and retest. If there is still an issue then your problem can be a throttle position sensor or the onboard computer. This is a hard one to diagnose without seeing the vehicle itself.

A few possibilities:
  1. Defective throttle position sensor (TPS);
  2. Bad idle bypass circuit or idle circuit solenoid;
  3. Cracked intake manifold, throttle body assembly, or bad throttle body gasket (most likely);
  4. Serious vacuum leak somewhere.

Gas pedal sticking. requires more than normal pressure until car starts moving

I had same problem on my 2004 lesabre, I waited until it was stuck and opened the hood and pulled on the throttle by hand very easily and could feel it sticking there, so I sprayed carb cleaner on the springs and around and through them. This loosened it up right away and have not had any trouble since, I did not spray anything into the throttle body, Good luck

2002 Buick Park Ave gas pedel sticks

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

My 1990 Buick Lesabre shakes at 40 mph what do I do?

Check front engine mounts. Open hood, hold brake pedal down, put car in drive, press gas pedal down a little and see if engine jumps up due to a broken mount.
