OK- what a fun afternoon and evening with my new scanner- Still getting that 0102 and 0401, the egr code- maybe I need to clean that anyhows- but I followed your suggestions- I pulled each wire from the plugs on everything- checking for good crimps, clean wires. I have to say I can not find a problem in any of the areas.
So, my question- where is the power coming from for the MAF? could a faltering alternator cause this problem? I have had some instances of headlights modulating on me, it seems to be while going through corners, transmission shifting I see lights dim and brighten occasionally. So, with the precision of the MAF device itself, I'm thinking possibly unconditioned power causing a problem? I'm not too proficient with this device yet, but I'm yet to see where I can monitor the power system with it. I can watch quite a few parameters numerically or in graph mode- and log it- but I'm drawing attention to the power obviously.
