2013 Jeep grand cherokee v6

Thanks, my local mechanic agreed with what you said but also said I needed to take it to the Jeep dealer as his computer was not powerful enough to isolate the problem. Local Jeep dealer told me it would cost me $130 to analyze the problem and didn't know what it would cost to fix it. Ain't that something ! I said I would think about it and left. Maybe I should move to warmer weather.

Yep some independent shops can’t afford the high end test equipment so unfortunately your stuck with dealerships for more complex problems. Thanks for the points
