Shudder at 30% throttle, no auto start, AC cuts out after oil change
I recently had a oil change / service at my local Ford dealer. The day after I noticed my auto start did not work. I did not think much of it and a day or so later was going up an over pass and went to accelerate and noticed a shudder followed by the truck almost completely stopping. Everything settled out and it ran OK. Still does this at 30-50% throttle consistently. Additionally, when the shudder occurs the AC blows hot for 2-3 min after the shudder. No faults, no wrench...2015 Lariat with 44,000 or so miles. Any help would be appreciated.

What engine is it? I have the EcoBoost 3.5L and when I first got my truck, this happened to me as well. Only difference is I got the wrench on the display as well. I changed the plugs and it was good to go.

Sorry about the key detail. 3.5 ecoboost. Has been great until now.
