i was checking for codes the other day and i pulled a code 42. the FSM says it a vehicle sensor. there is no page for troubleshooting. should i be concerned or looking for something? on a side not i'm slowly checking everything due to the lack of power while going up hill. i'm currently in lower alabama and the hills here are jokes ( i'm originally for up north ). on a staight away theres all sorts of power and get-up. going up and little ass hill in third gear at 35 to 40 mph is pissing me off. i'm starting to think its a gearing thing, A440, 33's with 4.11's on a OME heavy plus f/r. any way the code 42 thing, what do you guys think?
