The cel was on for the injector saying number 5 short circuit. Tested with multimeter and value was low. Truck felt like it was missing at times and would go into half power mode.

After they replaced the nox sensor they claimed it went into half power and threw a bad injector on 6.... They tried too drive it before recalibrate the scr maybe? Then they called me after and told me the cat is bad. I'm pushing back pretty firmly against this. Cat don't just burn up.
