on the eve or these new injectors coming Thursday and so far loosing my optimism anyone have thoughts on the eval purge valve? Would it or a vacuum leak near it cause a rich condition? Ive checked the hoses but I’ll be inspecting it and the hose again tonight.

The purge valve should only allow air / vacuum one way. If you can suck or blow both ways thru both ports, it is bad. The temp sensor MAY cause issues, but easier to see since your reader is real time is to take a peek at the coolant temp and see what it reports when the problem is happening.
finally a positive post!!! We have correct fuel trim I repeat we have correct fuel trim. Can’t believe new injectors would be junk but they where. New/reman mopar injectors are in and just did 50 miles with the code reader showing short term fuel trims all over 0 , -2 +3 back to 0 etc. long term dropping right to 0 at no throttle it was a great sight to see finally. Didn’t touch the coolant temp sensor so I’d liked the off brand on that. I’m going to drive it all day tomorrow and confirm but I’m feeling good about it finally.

Great to hear!!
No worries- another update. Total we have 800 miles since the head gaskets and about 200 miles since sorting out the injectors and rich condition. It was either the injectors or that hose fearing the fuel rail and a loose hose clamp. She made a tailgate event and Now I’m packing it for Colorado in June. On with the good times. Thanks for all the ideas and help.
