>My one friend said its probably one or 2 of my sensors that went bad
I thought the RPM gauge got its reading from the PCM (computer). I'd look for a dirty connector but first I'd suspect it's in the actual cluster assembly. I'd look for contacts there that have corroded where the cluster connects to the wiring harness. Bonneville people have some trouble with corrosion there. You might try the vibration method-hitting the cluster to try to break through any corrosion with movement enabling a fresh connection metal-to-metal. And there may be a module that interprets the signals from the PCM that's a part of the cluster. That may be failing. But I'd suspect connections first.

alright, yea i didnt think it was a sensor either cuase i didnt see how that really related to the rpm meter but at this point im lookin at all options haha, thanks for the help!

Having trouble with a new vcar we purchased. The car has 47,000 miles and the passenger side a/c blows warm. We charged the system to 35 lbs with no help.Moving the actuator under the glovebox was no help.There are 3 actuators in the back of the glovebox...has anyone fixed this problem before?

There is an electrical actuator motor on top of the heater box above the programmer. It's connected by a short set of wires. I think, think, that is the one for the passenger side. See if it's working. The motors can have gears crack and they slip on the axle.
The other actuator is inside the programmer and extends its rod along the bottom of the box to a white plastic arm that moves a door inside for the driver air temp.
the other actuators are vacuum and they are on the driver's side of the HVAC box.

Thanks for the quick reply..do I access the passenger actuator thru the glovebox?

Take off the passenger hush panel.
Take off the 7 screws along the bottom hinge of the glovebox. With those both out of the way you'll be able to see both and watch their actions with the key ON and when changing the settings on the dash or on passenger door.. One does passenger, one does driver. And I believe it's the bottom is driver.

I have a 95 buick lesabre custom. It is leaking gas and i need an engine diagram or something to figure out what the part i need is called so i can get it fixed can anyone help?

Why do you believe it's leaking gas? What are the symptoms?
There are places on an engine where gas can leak. There are connections on the flexible fuel lines at the fuel rails that holds the injectors.
There is a FPR (fuel pressure regulator) which controls the fuel pressure based on engine vacuum, sensing the demand for power from the engine. These in some cases were recalled because they could leak into the vacuum tube connected to them and let raw fuel get into the intake manifold where there usually is only air; occasionally a spark would ignite that mixture and the upper intake manifold would crack from the pressure inside.
There is raw fuel at each injector. There are o-rings around each injector (two) and these might leak with age allowing raw fuel to seep out.
Your brief description sounds like you are smelling gasoline and believe it's in the engine compartment.
You also can have fuel leak at the metal line from the gas tank which is under pressure by the right rear tire.
You also can have a fuel leak at the fuel filter in that line from the tank. The fuel filter is under the rear passenger's right foot. It's about the size of a caffeine drink can (Red Bull?). the connections there might be leaking.
At the back of the car rust is a major problem if the car doesn't get sprayed off regularly when the car gets salt underneath in the winter in the northern parts.
