Dodge Durango rough idle, stalls

Hello, sounds like a vacuum related issue if the brake pedal is hard, but then it could be a low engine speed that prevents enough vacuum from being created. Sounds like an air intake issue - if there is too much air and not enough fuel. Vacuum issues and air intake issues are likely caused by the same concerns. Stop the guessing; the auto parts store isn't performing a diagnostic test. You need a trained technician to assist. You've probably squandered quite a bit of money replacing unnecessary parts; perhaps it's prudent to spend a little money to get an expert opinion from a hands on technician? The repairs performed thus far do not (for the most part) appear to be directly related to the actual concern...and would not affect it in any way. https://repairpal.com/auto-repair-near-me That's a link to find a shop near you.
