Q: Car will start but will not run.

Hello, to whoever it is that can help me. I had a previous issue starting about 3 weeks ago. Spark plugs # 3, 4, and 5 starting going bad. Changed 4 and 5 but still need to change #3. Anyway, my wife dropped me off at work, went to drive home ( less than a mile) and my car stalled out. Wouldn't run again. She came to get me and I found out that the car decelerated, puttered and stalled. Was going up hill and wouldn't rev past 2200 rpms. Now if you try to start it, It will crank and turn over but will simply stall out after 1-3 seconds, If you hit the gas while cranking it will spike to 3000 rpms and then just stall unless you hold the gas pedal to the floor then it will putter for 10-30 seconds at around 500 rpms until it stalls. I've changed the fuel filter, spark plugs, ignition coils, and used fuel injection cleaner. I cleaned the throttle body with a tooth brush and car will run without the air hose attached but will stall if I reattach. Any suggestions before I spend more money?
