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

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.
