91 Ford F150 5.0 rough idle and wants to stall when put into gear
This is a brand spanking new block just eveything else is old. The crate motor is the 5.0 HO and I pulled the codes 412, 116, 126, 172, 332, 411, 114, 166, 112, 334. Any help would be great I cannot figure out which sensor could be causing everything to freak out.

I'm not an expert but here are what the codes stand for in my INNOVA code reader book.. No clue if these are accurate. Just going by what my code book says...I would double check to see if these are right because I did not look them up online.
112- Air charge temperature sensor below minumum voltage
114- air charge temperature sensor higher or lower then inspected
116- Engine coolant temperature higher then lower then inspected
126- Manifold Absolute pressure (MAP) or Barometric sensor (BARO) above or below normal
-OR-
126- Cylinder Identification Circuit Failure
166- Does not even list a code 166 in the book...
172- HEGO (HO2S) Sensor fault/lean ---Oxygen Sensor
332- Insufficient EGR flow detected
334- EGR closed valve voltage high
411- cannot control RPM during KOER low RPM check
412- cannot control RPM during KOER high RPM check
I think codes 411 and 412 are thrown because you have the vehicle turned off when checking for codes..."I Think."
Vacuum line issue?
MAP Sensor issue?
For the EGR codes it could be a sensor or the valve
Are you running Stock computer with Speed Density setup?
Below are links you can check out that may help I only browsed through them....Your guess is as good as mine. Good luck
