Does anyone have a clue as to why my IAT is reading is so low? It's not the MAF, I've switched it with one from a different vehicle. Mine also reads correct on that vehicle. The temps shown are basically room temp, key on, not running. I checked the MAF temp and it was 74 degrees. At least the coolant temp is right.
Would a larger gauge wire mess with values? The black signal wire from the MAF to the pcm needed to be lengthened, so I used a thicker wire to do it. I started looking for a problem because it was throwing a code for bank 1 & 2 being rich. It only seemed to throw the code when I was stomping the gas from a dead stop. I think the rich problem is coming from the fact that I am running a t-stat that runs at 182 fully open and the IAT reading cooler than the air really is. It feels a little sluggish when it takes off WOT in 2wd.
