Question type: Maintenance & Repair

Car is running those codes stalls for a

hesitation in the throttle after its done
stalling car also idles poorly things I've

Have you tried replacing crank shaft sensor?

Austin Smith

It's on the list :) I'll try it


Mine was acting similar thought it was a fuel problem. Had my car scanned came up crank shaft sensor. Not sure what code that was... The part is around 50$ it is kinda hard to get in right but it can be done yourself!!
