Default 2.5L/2.2L running problem

So from this link you will know which engine and spec I'm talking about.

The engine started but ran a little rough the other day. I had swapped the original Aux air valve and figured that was the problem. The engine went from 1000rpm to 2000rpm reving up and down and stopped then did run for a little bit once warmed up. So I put on my original valve. The engine runs smooth after starting goes up to about 1500rpm and then to 1000 and dies. I can start it again but it does the same thing, like running out of fuel although it smells from the exhaust that it's running to rich though. I did see I had missed a plug to the small air box under the intake manifold on the left viewed from the front. So I plugged it in but the same problem. Any clues guys? I've checked all the plugs and pipes and all seems in order. The 2.2L ran sweet before I did this conversion.
The engine sounds fine with no odd noises.
To me it's like it's to cold and not getting enough fuel even though it smells rich. Tomorrow I'm going to pull the plugs to see what's happening in there.
