Brad I was sceptical about your comment that this problem of driveability(bucking when lights or heater blower were on) was most likely related to D-Jet/lean/rich mixtures. After reading your post I reset my ECU to the factory mark and reset the idle to @1,000rpm. Voila...most of the problem disappeared. I also repositioned my K&N filter which had slipped off the air box flange..ie. no filtering and I pulled the hoses on the AAR valve to make sure it was functioning properly..it was. I haven't been able to drive the car on a moist/wet night to see if the problem still exists..but so far this seems to have eliminated most of the problem. I thought that particularly on damp evenings due to wear on the tracks of my Throttle Position Sensor this condition could cause excessive arcing that may have been causing the bucking. By setting the ECU to factory mark I can smell that is is idling much richer than before. I did notice some bucking when the motor is still not warmed up completely when both headlights and heater blower are turned on but it is not as severe as before. Seems to me the more I learn about these cars from all you people out there the more I realize I need an AirFlow meter.
Hey Bowlsby...someone should bring one if they have it to our next breakfast meeting. I'll keep everyone posted on whatever I next discover.
