Did you check the fuel pump relay ?You would need to use a fuel pressure gauge and check pressure before you crank the engine. When you turn the key switch on, the pump relay is supposed to provide power for 3 seconds to boost fuel pressure.If fuel pressure is ok, the coolant temp sensor could be telling the computer the engine is warmer than it really is.

Drain plug for what? If you mean antifreeze it is on the front drive side corner. You have to move the plastic guard a bit to access it.

usaually on the left bottom facing car or unerneath in same location

Unless you are mechanically savvy this a job best left to a mechanic as it is an involved process

Get your brakes checked

before going in a tire shop for an alingment rotate your tires

So your control is not good it dont turn the vents to you

Vapor cannister hose under hood could be off or cracked.

Well you could remove it and have it bench tested at a parts store.Or check the connections for voltage with the key switch in the start position.If the small wire does not have power, you could have a problem with the neutral safety switch or the VATS security system.

The resisters on the back of the odometer fell off. they can be re solder if you can find them. That is what happened to mine

The upper intake plenum is leaking coolant into the cylinder heads. The head gaskets on this motor are awesome. So, chances are it's the upper intake plenum. You can check this, by removing the vacuum hose that runs between the upper plenum and the brake booster. Stick your finger in and try to touch the top of the lower intake manifold. If your finger is wet it the upper plenum. You might as well replace the lower intake gasket while you're performing this work because they are prone to failure also. Use a shop vac to pull any coolant out of the cylinder heads. Get brand new spark plugs because the old ones are probably fouled. Once you get the plenum and gaskets replaced, remove your fuel pump relay and leave the spark plugs out and turn the engine over repeatedly for about 10 seconds to push any excess coolant out of the cylinder heads. Then, put the spark plugs in and turn the engine over for 10 seconds again. This will burn excess fuel as coolant out. Then, replace the fuel pump relay to allow fuel to be pumped into the heads. Car will smoke for a few when it fires up, but will clear out quickly. CHANGE THE OIL! Twice within a week if possible.

Pull the instrument cluster. These are prone to resistors burning out on the back of the cluster. It happened to mine. You'll need a soldering iron. I believe there are a couple of YouTube videos out there for this particular problem.

I'm leaning toward either the idle air control valve (IAC) or something in the fuel system, i.e. fuel pump, fuel filter, injector. Pull a fuel line off of the fuel rail and verify that you are getting fuel the injectors. Most likely, it will be the fuel pump.

It's on the passenger side of the motor just below the belt tensioner assembly.

Turn the key to the "on" position, but do not start the engine. Access the low tire reset button by opening the passenger door removing the fuse panel cover located on the passenger side of the dashboard. Press and hold the red "reset" button until the light begins to flash and goes out. Release the button. Replace the fuse panel cover and you should be good to go. If that doesn't solve it and your tire pressures are all correct, then it's electrical. That light is only supposed to come on when one tire reads 12psi lower than the other three.

Could be a dirty throttle body or a faulty idle air control valve.The computer controls idle speed by regulating the amount of air entering the intake thru the throttle body.

don't want to start after it sets about 30 min.,if it does start it will run rough and then die.let it set and get cold it will start.What is the the trouble?

problem with the park positioning switch on the back of the wiper motor That bit with all the wires. it can be reset but really a replacement unit is quicker
