After i replace the pcv valve in my 2013
dodge avenger. The engine loght comes
back on. And its the same problem. The
pcv valve. That i just reolace same day.
Any idea why? Any body please.
You need to have the codes read to know what is going on. I would double check the PCV though to make sure you don't have a big vacuum leak.
Check the associated hoses in that area for a leak, especially the one hooked up to the PCV valve.
