MAF issues and battery
Firstly, thanks to all who post on this forum. I have had an 2006 Alfa 147 1.9JTD 16v for less than a week and thanks to this place I have already (with zero car knowledge or experience) fixed five issues for almost no cost.
I was experiencing heavy vibrations when idle, and low power response at <2k revs. After much reading and confirming that the EGR had been recently cleaned and checked, I disconnected the MAF sensor and did a throttle reset. The performance improved instantly, so it seems that the problem lies there (I tried a throttle reset alone prior to disconnecting the MAF to no avail).
I am on an extremely tight budget, so I will attempt to clean the MAF sensor before looking at replacing it.
Forgive me if this is a silly question, but I was just reading about how the MAF sensor works and I was wondering if a battery problem could cause the MAF sensor to misbehave?
I have a 646 450cca battery which has tested as fine, but I get VDC warnings which made me consider trying a 652 battery instead with higher amperage and CCA. I will only be able to do this test in January though.
So my question is whether I should do the battery test before cleaning the MAF, or if these two things are totally unrelated and I should go ahead with the MAF cleaning?
