So i recently replaced my 02 sensor(s13) and my car developed an idling problem. When I would go out of gear to coast/brake to a stop the idle would dip way down and sometimes stall then it would go back up to 400 if it didn't and then slowly back to normal at 750 or so. I posted about this about a week ago and a few people suggested cleaning the MAF, but before I got a chance the problem "fixed" itself, but now the car has gone back to backfiring like it used to. Does this tell any of you anything? Might it still be the MAF? Where is it located and what does it look like... Let me know, thanks in advance.
P.S. any of you had problems with your rear calipers sticking. I don't use the e-brake anymore, but they still stick on and off, sometimes really badly. Sofa king annoying.
