Ok..
P0106,0107,0108,0109, 0098..
Also, service AdvanceTrac light came on.. this happened randomly while driving.. no recent changes to anything..
I have replaced MAP sensors with 3 bar at the manifold and one MAP at tube. Replaced throttle body, checked for vacuum leaks, and took off my Catch can and put the stock hose back on. Had a mobile mechanic come and check continuity and voltage.. getting 5volts which is correct so wiring is good.
I did datalog and noticed when I revved car (what little it could do).. number for the MAP did not change at all.. almost like it was not reading.
PCM?

Sorry for the stupid question. So you have a tune correct? You need a custom tune for the car to work with a 3 bar sensor at the manifold. If you dont have a custom 3 bar tune then put an oem map sensor back on

Hello!
Correct, have the GH tune going on 2yrs now. With the 3bar. Replaced 3bar with Ford OEM map sensor, no change except an additional code for 02's. Also replaced the map at the tube as well.
Also tried the Ford map and returned car to stock.. hoping it would fix or run differently. No change.
I would expect on the datalog the Map reading would change when revving or idling like barely though.. instead it was stuck at same number.
