Thanks to EagleScout yesterday for your help. Swapped in new plugs, breather and air filter. Checked and adjusted TPS. Condition still exists. Sounds like a miss when running.( New cap, rotor and wires as well recently) Engine seems to shudder. I’m leaning toward more of an engine issue then sensor. Presently plan to pull off valve cover and check valve springs for any damage, to maybe explain a valve getting hung up or inoperative. I may end up changing out valve seals because oil is still getting into combustion area. I haven’t ruled out rings yet. Like I said earlier for it to be solely the rings, every cylinder would have to have failed since all 4 plugs were oil fouled. At 140 on the engine I can’t imagine this to be the case. Will post more when I uncover more! 2.5 Jeepers Creepers😎
