Thanks Tony, yes at idle it is shuttering and still stalling. I can keep it running if I keep the throttle at 1/2 or above. During the cleaning process of the IAC and fuel filter replacement I had the battery disconnected. So I assumed the computer would start from fresh and have to re-learn the sensor characteristics. Am I wrong??

By the way what are fuses 4 and 11?

And would you happen to know what the sensor is on the bottom of the intake tube in-between the MAF and the thrttle body?
