[QUOTE="hingedthinker, post: 1884354, member: 38159"] Glad I found this thread. I have new to me 2018 Rap for four days. Love the truck and no issues except the one described here in OP. On WOT from stop or highway at 80 to WOT I get a very noticeable engine shudder, almost like the ecu cutting fuel on/off quickly. This morning I tested and replicated again. Noticed transmission stayed in 7th gear but still shuddered. Feels like the engine not the transmission. Ellison fixes seem reasonable other than the costs of those parts. Does my description sound familiar? thinking i will start with new plugs, boots and coils. then catch can, new thermostat. [/QUOTE]
