Sputters and dies on cold start, significant drop in gas mileage.

When I start the engine cold, it does not settle into an idle. It sputters and dies, so I have to press the gas pedal to keep it running. When it warms up, engine runs smoothly and idles regularly. Also have a significant drop in gas mileage. 1.9L 2WD 4Spd Manual Trans. SOHC Gas Engine.

You need to rebuild the carburetor or clean the choke linkage and make sure the choke valve closes cold.

The engine sputters and dies when it heats up. Is this Vapor lock? On cold start it works great and idles just fine but as it heats, the engine starts choking and soon dies out. If this is vapor lock, how...

sounds like the reason it starts and idles fine at start up is your choke is functioning... as your vehicle warms up.. the choke starts to kick off... Inspect your throttle body and idle control motor.
