My truck did the same thing today.Where is the G103 & G104 wires located?

 

I'm still looking for them 2.

 

Top right rear edge of block and rear of left cylinder head.

 

Thank you, DrX. Much appreciated!

 

Not to start any chit but mine had the same problem on the first turbo tune that I aquired from EFIalchemy it ended up being the tune, he gave the money back to me and then on the third tune I got from Hinson supercars it did the same thing ounce we got it all tuned up and went for a drive same codes and everything, it is something in MAF table that is reading more than it is supposed to, he knew exactly what to adjust and that was it, so the first tune was probably good just didn't know what to adjust I wish I could remember what he adjusted!
