Check the tps.

Plug the vacuum line you unplugged and the idle should come back. Change your air filter and the map sensor. check for correct coolant level and replace the coolant temp. sensor. This sensor affects cold starting and idle through the ECU (open loop mode, rich fuel mapping and 1200 rpm idle) It should go to closed loop mode in the ECU once engine warm up is achieved ( lean fuel mapping and normal 900 rpm idle). Do not unplug anything else till you perform an OBDII scan of the stored fault history

Go to Autozone, Advance, etc.. any good parts store and OBII scan done (fault scan) they do this FREE. Scan will tell you what sensor(s) to go after to fix. Once you repair or replace sensor have parts store reset your light.

My first guess would be the fuel pump. Alot of defective pumps will operate until they warm up.

The first thing I would check in a situation like this is the Fuel Pump.

Your fuel pump is physically inside the Gas Tank (which is located between the rear seats and the trunk/spare tyre).

However, the control unit for the fuel pump/motor is right on top of the tank. My experienced mechanic gave mine a couple of bumps with a small object (like a small pipe to reach the box) to kick it back into operation.

Here's a quick 15 minute test:

Try this: keep the tank -Filled Up- this will help to cool the Fuel Pump which sits in gas inside the tank.
-Put your keys in the ignition and turn to stage2 (right before you begin to turn the engine over),
-Go around to your trunk and give the Fuel Pump a couple bumps with a tool that will not hurt it (it is covered in solid plastic).
-Then try cranking the engine while pressing down on the gas pedal, one of three things will happen, 1) The engine turns over and everything is gravy! 2) It cranks but doesn't start up 3) It cranks but doesn't start and you can smell gas from the engine bay.

If #2 is you: then your fuel pump has hit some scummy **** and doesn't want to work without repair or cleaning, try giving it another knock or two with the electrics in the car turned on. Maybe have a friend crank the car while you -tap- on the fuel pump.

If #3 is you: Check your spark plugs, they could be misfiring.

If all above fails I would start thinking that you engine idle valve is dirty and needs a quick clean.

Best luck!

Check the air filter hose. My '99 Protege was idling rough and would sometimes shut off. The air filter hose was cracked half way around. I replaced it (easy just loosen two hose clamps and pull out the sensor) and the car is running fine.

Clogged Catalytic Converter. What happens is as you push down harder on the accelerator you force more gas into the system causing a slightly richer mixture and more exhaust flow is neccessary. The easiest way to look for a clogged cat is when it's dark out take it for a ride causing it perform it's problem look under the vehicle if the cat is literally glowing red hot you either have a clogged cat or an extremely rich fuel mixture.
