So this code is popping up now. I have a 96 gt.

I have a tuner and when I had the bama tune on, it still popped up. To my knowledge this is an evap code and is saying something is wrong with the purge flow canister? Heard it's common on 94-98s just wanting some insight on it and knowing the right path to take to fix it

P1443 - Very Small Or No Purge Flow Condition. A fuel tank pressure change greater than a minus (-) 7 inches of H 2 O in 30 seconds has occurred with purge (fuel vapor) flow less than 0.02 pounds per minute.

*Blocked fuel vapor hose between EVAP canister purge valve and FTP sensor.
*Blocked fuel vapor hose between EVAP canister purge valve and engine intake manifold.
*Blocked vacuum hose between EVAP canister purge valve-solenoid and engine intake manifold.
*EVAP canister purge valve stuck closed (mechanically).

This is all taken from CliffyK's link and is 100% correct. This is what causes the P1443 code! To fix it, just like Cliff said "Check for blockages between the fuel tank, EVAP canister purge valve and engine intake manifold. Check obstructions in the EVAP canister purge valve diaphragm and ports."
