1998 DODGE DAKOTA

Could someone please give me a hand, bought a 98 dakota a few months back and now I am having mechanical problems with it. V6 stnd and in a ll gears it will lose power and backfire when it wants, just tuned it up plugs/wires.
Took it to AutoZone and had "check engine light" scanned and it came up with code P0443 which almost everywhere online says P0443 EVAP Canister Purge Control Solenoid.

I bought a purge control solenoid from AutoZone and installed it myself, but still having same problem and the check engine light stayed on. Placed a little soap and water on 2 rubber hoses that connect to solenoid as far down as I could, but could not detect any leaks.
Any suggestions?

The error code P0443 in a 1998 Dodge Dakota indicates a problem with the Evaporative Emission Control System Purge Control Valve Circuit. The purge control valve is part of the vehicle's emissions system and is responsible for controlling the flow of fuel vapors from the charcoal canister to the engine intake manifold.

Here are a few possible causes for the P0443 code:

Faulty Purge Control Valve: The purge control valve may be defective or stuck in an open or closed position, preventing proper control of the fuel vapor flow.

Wiring or Connector Issues: There could be a problem with the wiring or connectors associated with the purge control valve. Loose connections, damaged wiring, or corrosion can interfere with the electrical signals and trigger the code.

Charcoal Canister Problems: The charcoal canister, which stores fuel vapors, could be damaged or saturated. If the canister is clogged or malfunctioning, it can affect the operation of the purge control valve.

To diagnose and resolve the P0443 code, you can perform the following steps:

Inspect the Wiring and Connectors: Thoroughly examine the wiring and connectors related to the purge control valve. Look for any signs of damage, loose connections, or corrosion. Repair or replace any faulty components as necessary.

Test the Purge Control Valve: You can test the purge control valve using a multimeter. Consult a repair manual or follow the manufacturer's instructions for the specific testing procedure. The test typically involves checking the resistance and functionality of the valve.

Check the Charcoal Canister: Inspect the charcoal canister for damage or saturation. If it appears damaged or saturated, it may need to be replaced. Also, check the hoses connected to the canister for any leaks or blockages.

Once you have identified the specific issue causing the P0443 code, you can address it accordingly. Depending on the severity of the problem, you may need to replace the purge control valve, repair wiring or connectors, or replace the charcoal canister.
