96 Ranger, "popping" sounds from Engine compartment
After truck reaches idling temp, and stops at a light, "popping" sounds come from engine compartment. Once truck is moving a back driving sounds stop. Might be connected to serpentine belt or timing issue??

If it has been awhile since the belt was changed it may be a good idea to change it and get a timing light and check the timing also make sure the beads in the catalytic converter is not releasing and starting to plug up the exhaust system

do u have a check engine light coming on? if not the plugs are not the problem a miss will trigger a check engine/service engine soon light, most likely you have a dirty automatic idle speed control motor.
Possibly you have a leaky or cracked exhaust manifold. After the engine heats the metal expands and creates a larger gap. As the engine speeds up the engine noise overcomes the exhaust leak noise and you don't really notice it much until the vehicle gets in to a hard pull or comes to and idle.
if your obd2 scanner fits the connection you have obd2, obd1 connector is way differnt.
your code p1443 Control System Canister Purge Valve (Mechanical) Malfunction Monitors the fuel vapor flow between the engine intake manifold and the EVAP canister. The system failure occurs when a leak or blockage between the intake manifold, the EVAP canister purge valve and the EVAP canister is detected by the PCM. l Pinched, blocked or plugged fuel vapor tubes/hoses (except between fuel tank and EVAP canister) l Damaged EVAP canister l Disconnected, cracked or cut fuel vapor tubes/hoses (except between fuel tank and EVAP canister) l Damaged EVAP canister purge valve Check for audible vacuum noise in the engine compartment or significant fuel odor in the engine compartment or near the EVAP canister.

I figured out what was going on. supposedly on ford rangers the Idle Air Control Valve (IAC Valve) goes bad. i got a trouble code looked it up and sure enough it is the IAC Valve. Under 100 bucks for the part
