Not much help, but it might point you in the right direction.
Okay, I saw a couple of things that doesn't sound right.
3. Replaced Choke - Your car doesn't have a carburettor, so there is no "choke". What you would look at in regards to this is the coolant temp sensor (two pin plug near the thermostat housing, yellow I think). Not really relevant to your issue though.
4. Adjusted Throttle Sensor - You usually don't need to do this. Is your car automatic?
9. Fuel Filter cleaned (SENSORS READ FINE, BUT SOMEONE SUGGESTED THIS MIGHT BE THE ISSUE and needs replacement) - You don't clean the fuel filter, you replace it with a new one. I forgot the exact price, but I think they go for about $25.
10. Air Mass Filter cleaned - I'm guessing this is the air filter? Throw it in the bin and replace with a new one. Paper air filter (Ryco A360) go for $10-15 dollars.
I can think of two things:
1. AFM - the air flow meter (on the air box) is playing up (clean with contact cleaner as mentioned). Might need solder fix (search in the how-to section), or replacement with a known working one.
2. IAC or AAC - auxillary air or idle air control valves on the intake plenum. Usually you take them out carefully and clean them up. I think they is a guide in the how-to section.
Does it run fine when it's cold?
