My 98 3.8 v6 is giving me a P0131 and P0443 had to replace IAC because it was damaged on the inside and replace all vacuum lines all the way to canister, just looking for a little direction or anybody that has had these codes before, still reading into what VMV circuit fault is but just thought I'd see If anybody had any helpful info . Thanks!!!!

Hi, the DTC , po131 is O2 sensor on bank 1. and the po443 is the purge control valve. Check the purge control solenoid to make sure it is working .the solenoid maybe causing your car to run lean or rich. throwing off the O2.

Don't forget to check the rubber tubing that connects everything; if dry rotted it will need to be replaced.

Cheers......
