So I installed a new ported intake manifold, and when I got everything back together, no CEL, idle is a little rough, but the truck ran great except the Transmission wouldn't lock up... strange I think since it only has 6,500 miles and I baby her...

Next time I start up the truck, the transmission is locking up no problems.. but I get the following two codes:

P0106 MAP sensor - manifold absolute pressure barometric pressure circuit range performance problem
P0443 - Evaporative Emission Control System

I went back and didn't see any obvious disconnected...

Anyone get any of these codes before??? What was the resolution???

I'm going back and checking the MAP sensor (on top of the manifold on a TBSS am I correct?)

I checked the MAP kpa (using Dashhawk) was right where it should be a cruise 35 to 40 kpa...

So I checked the emmissions control connector, and it was not connected...

So that explains the P0106 & P0443....

Now with all the extra air I got two new codes....

P0171 - Lean Bank 1
P0174 - Lean Bank 2

I don't know if that has to do with the fact that I reset the fuel trims while the car was running or not... So I disconnected the battery and will try again tomorrow...
