well, initially I had the vacuum leak/idling problem. During that process I had changed all the intake manifold gaskets, seals, O-rings, IAC Valve, MAF, TPS sensor.

My car ran badly for the first 20 miles and then everything ran real good. 400 miles later(today) the car would start and die immediately. Regardless if I start the car and immediately shift to gear, it would die. One thing I did notice was before, all I had to turn my key and the thing would start; Now, I have to turn the key and count till 5 before it starts. Also, last night's drive was a little rough. It seems like the car was hesistating/jerking very minutely.

There is a CEL that came on last night but I cannot get to it because it won't move.
