What is wrong when my car is throwing smoke out of its heating system?
Are you sure it's "smoke"? Hot water/antifreeze from the engine enters the inside of the vehicle into the heater core. The heater core looks like a little radiator with fins. Air is blown across the fins to get heat from the water into the car. If your engine is hot, and you develop a leak in there, it might appear as smoke but is actually steam.
If it IS smoke, I'm not sure how it could get there. Maybe an electrical wire is grounding out but there are usually no wires inside your heater core. There's virtually no way for exhaust to get in there either.

I have 93 Mercury Capri that has overheated a few times in the past week. I replaced the thermostat but now it wont stay running unless I keep it at like 2 grand, any advice?
My guess is you've got a bad head gasket. Pull off your radiator cap. Stick your finger in there and feel if it's "oily" and if the level seems low. Also, check if your oil level is higher than normal and looks a little cloudy instead of a nice solid green or brown.
If you have any of these symptoms, the antifreeze is getting into your oil through a bad head gasket.

How a car a.c works?
Correct except high pressure "liquid" from the condenser goes into the expansion device. When it enters the evaporator, the pressure drops and THEN it changes state into a vapor. Ths is where the most BTU's are at, At the "state change".

What is the function of a PCV valve?
It's not just for emission control. You have to allow the positive pressure created by the engine to escape

Which one is correct whether sitting plan or seating plan?
Seating plan is the correct usage.

The plan is by those who are thinking how or where the participants must be seated; not by those who are going to sit down. In other words the plan is for seating some one; not for us to sit.

I need how to replace intake manifold gasket on a 1996 Chevy pickup k-1500. motor size 510?
Long process.
Drain all your anti-freeze.
Carefully remove everything attached to the manifold noting and marking or tagging all the parts, especially vacuum lines for ease in re-installing. Remove the wires connected to the distributor and then remove the distributor. ( I take off the cap and note where the rotor is pointing). Remove all the intake manifold bolts. VERY CAREFULLY, use a putty knife in the front of the intake to try to push between the manifold and the block. Once it's loosened, use a small pry bar (again, carefully) to start prying the manifold loose. Once it starts to lift up, you should be able to use your fingers to pick it up and out of the truck.

Clean all gasket surfaces until you could eat off of them. When your done, use a little laquer thinner on a clean rag to make sure there are no oils left on the mating surface. Clean all of your bolts paying particular attention to the threads.

Put just the tiniest smear of silicone in a few spots on the head where the gasket is going to be. Let it tack up for about 5 minutes. Carefully put the long gaskets in place and hold them there with your bolts. For the two front and rear rubber gaskets, use a gasket sealer designed for rubber. Put a light coat on the block adding just a little more where the block meets the head. Let it tack up for about 5 minutes. Add the rubber gasket sliding the little ends under the big gasket you put on earlier. Add the rubber gasket sealer again to the top of the rubber gasket and let it tack up for 5 minutes. Pull out the bolts holding the first gasket in place. If you're lucky, it will stay in place. Slowly "ease" your manifold into place trying not to disturb the gaskets. You want to come strait down and not have to move it forward or backward and risk moving the gaskets. Put an 1/8 inch bead of silicone from the bottom up halfway on the threads of your manifold bold bolts and thread them in with your fingers. When they are all in finger tight, use a wrench to give them just (1) turn. Start in the middle of the manifold and work outwards both ways. I would let it sit like this overnight and let the gaskets and sealer solidify into any irregularities in their new home.

You'll need to find out the "torque specs" for your manifold bolts. Make it a slow 3 stage process. Torque them all 1/3rd of the torque each stage in the same pattern as you did before. Start in the middle and do a criss cross pattern. If you are on the drivers side lookin in, (from the center working outwards both ways, lower left to upper right, then. lower right to upper left. This will insure you don't get any warpage and everything goes down nice and flat. Go over the bolts one last time and check the torque.

Put your distributor and wires back in. Re-install everything back onto the manifold. Refill your anti-freeze.

Start it up and let it run for about 15 minutes carefully listening for any air leaks, oil leaks etc. Let it cool down and re torque your manifold bolt. You may not be able to get a torque wrench on all of them. Use a wrench on one that's already torqued to "feel" it and try to apply that same "feel" of torque to the ones you can't reach. give it a couple of days to a week of driving and check the torque on the bolts again.
Done.

NOTE: the front and rear gaskets are the most notorious for failing so take you time in this area especially. Do it right the first time so you won't have to do it again.

Why does my gas pedal stick drastically when I slow down from freeway speed? So much that I cannot push it down to give it gas. It feels like it wants to stall. I drive an 01 Chevy Tahoe and recently had the fuel pump and fuel filter both replaced.
In addition to Craig's answer, make sure the linkage is nice and clean. Use some carb cleaner and a wire brush if you have to. If your vehicle uses a throttle cable, try to squirt a little WD-40 into the cable sleeve. If it's linkage, squirt a little on all the hinge and pivot points.

I have a 95 Nissan truck, when the key is in the accessories position my fuel pump starts running, the truck will attempt to start but wont turn over, is this a problem with my relay, please help?
Your truck shouldn't be trying to start in the "accessory" position. I would say your ignition switch needs to be replaced.
