Okay, I'll try to make this short sweet and simple. For reference I work on my own car as much as humanly possible.
Started car one day, packed it up for a trip, the AC was on, and suddenly it stalled out. Started right back up no problem, then stalled out again.
I immediately replaced the camshaft and crankshaft position sensors, because I know that those can be an issue.
This did not help the issue, but I finally got a CEL code. The code stated that the RPMs were not high enough. I googled it, easy enough, I replace the throttle body which contained the new intake air control valve. I did an idle relearn on it.
It continues to stall at idle. I have a new O2 sensor upstream and downstream, but I am receiving check engine light codes for both O2 sensors, as well as running too lean.
I am thinking vacuum leak, but the brake cleaner spray trick did not produce any effects that would lead me to the leak area..
**Once I'm going on the highway, I could drive 10 hours and not have a single problem, which I did because I had to go to Tennessee for work.
**My valve cover gasket has needed replacement for a bit now, is it possible that the issue could be related to the PCV valve and I should just change the valve cover when I replace the gasket?
Any ideas would be helpful.
