1998 Dodge Dakota 6 cyl Two Wheel Drive Manual 140K+ miles

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?

Hello,

The code you had pulled is listed below.

P0433 Heated Catalyst Efficiency Below Threshold

The back firing usually indicates a timing problem. Check the timing.

Sorry for delay was out of town.

Did you hook up a scanner and clear the code?

Have you checked the vacuum lines?

Well, no I have not cleared the code since the problem still exist. I followed the 2 hoses that come out of the Purge Control Solenoid, one goes to the TBI and the other under the hood. It is this one that I followed and notice it goes from a 5/8" rubber hose to a smaller diameter more plastic hose all the way to some sort of box the size of the catalytic convertor.

It has a plastic sheathing cover to it so I coulod not locate a tear in the hose. Called Autozone and was told they only carry "rubber" hose and not aware of a plastic smaller diameter hose.

Ok,

Have codes rechecked for any new codes then clear them.

Here are the Vacuum Diagrams one for California Emissions and the other of course for all others...
