Is it possible for the throttle position sensor, or even the speed sensor to malfunction and give wacky readings without tripping a code and displaying check engine light? Just curious..My truck has no cruise display when button is pushed but what has got me thinking is that I have noticed a bit of a stutter when tranny shifts gears...especialy when pulling the ski-doo trlr under acceleration. After the input on this thread it makes me think the two are related, but I do not have any codes showing...What do you think?
