Not any mechanic could diagnose it. Most will probably scan for codes and then do basic testing for circuits/components related to that code. Rather than knowing these trucks and what else can skew readings. Are there no reputable shops in your area ?

Ok, so an update. Shop recommends new maf sensor and #4 glow plug. In the meantime, I bought a scanner, Autel, and from what I can see, the maf sensor is within parameters. It does live data, so, what can I look at, besides the maf.
