So I was just driving along minding my own business and the wrench light came on my elms dropped to 1k and had zero throttle response. Like car was in limp mode but chugging. I stop. Turn it off. Start back and make it another mile till it happens again. Wash rinse repeat and I am able to continue on. Doesn't happen again for 45 miles on the hwy and same thing. Does it twice and hasn't happened again yet. Strikes me as a bad sensor or something but im totally lost. 46k miles. 10se 2.5l. Anyone?
