Took my car to the dealer to get fixed. It has idling problems where it will almost die, then rev back up. This happens on startup and sometimes when I come to a stop while driving. I also had a CEL and hence the dealer visit. I got the car back today, they replaced the MAF sensor, cleaned the EGR tubes and did a carbon flush. $625 later, I got it back but the idling problem is still present!!! Any thoughts on how to handle it with the dealer and what the problem might be (seems the techs don't know)
Thanks
