if my TPS is not set correctly could it cause it to throw a code for the MAF and itself, also could it cause the truck to back fire at high rpm if not set correctly or not working.

code
24: intake air temp open or short in signal
31: Manifold and or airflow meter sensor signal
41: TPS Sensor signal open or short

 

Bumppppp

 

I'd start ohming out that afm

 

Probably not. Post your AFM and TPS resistance check results.

 

Ill post my readings in 30 mins, is there a chart i can use as refrence. Also is there a 91 full vacuum diagram my vsv is acting strange. Also i read you put in the dizzy at 5* on the crank with the rotor at 12* on the small dizzy gear can anyone confirm this, and is there actual marks on the dizzy that indicate 12* or just rotor facing 12 oclock.
