need recommendation for mopar knowledgeable garage in Chicagoland

There's a thread on Moparts where a guy was having the exact same problem. Majority of the responses said Hall Effect pickup in the distributer was bad, and a few said MAP sensor. He tried several things before putting the MAP sensor on it, and that fixed it. Jim Rhinehart has a shop in the Chicago area. He's a member here and on Moparts. Rhinodart is his screen name both places if you want to send him a PM.
