Brought Dart to shop to fix idling issue and car runs like s**t!

Thank you everyone for all the input and info. Yes I’ll look into having a leak down and compression test done because that will give me affirmation that I have good cylinder pressure and that the valves are opening and closing properly. I’ll also keep everyone updated on the outcome of this. I just wanted to ask to clarify AJ that I shouldn’t stay with the mopar electronic ignition and no vacuum advance? I should go back to the original distributor and points? I’m determined to get this situation ironed out and made right. I can’t wait until my garage is completed and I can continue to learn and work on my cars in a comfortable garage, take my time and do things correct. Outcome pending.
