No, Not an EGR valve. I would go with an electrical problem. As the speedo jumps, do other needle jump or move also? If so I would start at the dash. Some cars wont run or even start without the dash working. Could be as simple as a bad connection at the plug. Some times you have to go a little further by squeezing the female connectors down a bit. Then I would pull all the fuses and check to see if they are good . Pulling them takes care of any corrosion/contact issues. Next would be to check power and ground points.

SOURCE: pops back through the intake when it is cold runs

This problem can be caused by defective spark plug wires that are cross firing due to voltage leaking to a nearby plug wire as well as a flat camshaft lobe.

Why does my 2005 elantra uses excessive amount of fuel?

Maybe there is a faulty sensor or the car's engine is in need of a tune up which consists of new spark plugs and wires and new air filter..

What would cause this vehicle to use execessive gas.

1) dirty air filter

2) vacuum leak

3) false reading from mass air flow sensor

4) false reading from coolant temperature sensor

5) improper tires inflation

6) topping off gas when fill-up (soaking emission lines with fuel)

7) Positive Crankcase Ventilation (PCV) and breather element clogging

8) Exhaust Gas Recirculation(EGR) Valve stuck with carbon and EGR passage tube is block with carbon.

9) low or dirty transmission fluid + filter (if it's an automatic)

10) excessive load

The air mixture screw does not make my mixture richer or leaner

Unless your vehicle is really old and has a carburetor there shouldn't be an air mixture screw. Air and fuel mixture ratios on engines with Electronic Fuel Injection or EFI are controlled by the vehicle computer witch receives and sends information to and from a slew of different sensors like the oxygen sensors, throttle position sensor, the idle air control valve, Etc. Chances are you have EFI on your vehicle. If your engine is running rough or lacks power, try a complete tune up. New spark plugs/wires, new fuel filter, new air filter, oil and filter change, new oxygen sensors. Try running a bottle of injector cleaner and a bottle of water remover through the vehicle and see if it helps. Hope this helps.
