Hi Alan,

I am not familiar with this vehicle but my gut feeling is that this is a fuelling problem and not ignition related. I would be interested to see the 4 gas readings at idle and fast idle which will give you a clue because I feel it is too lean and careful attention should be paid to the MAP Sensor. My Vacuum gauge reads in "hg so your reading in mb means nothing to me but would be interested to see what the conversion is. Best of luck
