2009 Outback. 190,000 miles. Head gaskets, all belts, water pump, cat, plugs, wires, coils, batteries all new within 2500 miles.
The other day, inexplicably, the car died at a stop light. Now, it works fine for about 20 minutes and then it starts stuttering and freezing. If kept at higher RPMs it runs fine. It also works fine after cooling for a while, but the problem returns after heating up again.
I have checked the temp sensor, crank sensor, MAF, air fuel sensor and EGR. Everything seems to work as it should. I have done the re-learning procedure at work 4 or 5 times. There is no difference.
One strange thing is that there seems to be no connection between the temperature gauge and the problem. In other words, there is no noticeable rise in temperature before the issue starts. The car is at temp and stays the same during stuttering and stalling.
Can anyone help?
Thank you in advance.
