2017 Yukon came in with a P0300 random misfire and a MAP sensor performance code. Easy to blame sensors… but this one went deeper.
Tracked it down to a broken valve spring causing random misfires and false sensor readings. Replaced the spring, cleared codes, and it’s back running right.
This is why diagnosis matters. Mechanical problems can trigger sensor codes and waste time if you’re not careful. 🔧 #MechanicLife
