I hooked up the scanner and I got PO 103, I checked in the book and " Mass or Volume Circuit High input " is what it says. I have no clue what it could be, but my friend was telling me that sometime people get this code whenever they fill up the gas while the engine is running, wich i dont. Yesterday at one point I started the engine but I guess I didn't give enough time so the engine started but shut it off, so I crank it up again and then the engine started no problem I believe I got the code just after that. Does anyone one had this code before and would possibly know to what it is related ? I erased the code, but I'll see if it come back later today. The truck is running fine but I like to keep my vehicle in the best running condition.
