So guys I replaced my old Barometric pressure sensor cause I was having a P2227 code, so replaced it, then the new one came, and I put that in and got high circuit codes for that, and then developed an idle issue after warm up. Mind you guys I've had this same problem since my fuel pump went out. Mind you I've changed my purge valve right after that as well just to be safe. So here's what I'm dealing with after car warms up I'll have normal idle at 700/750 RPMS and then it'll Decel to 500 and run like dumpster fire for a few seconds then catch it's bearings and then decel then die. All this after putting in the new BARO. Any help is appreciated guys. Fuel pump went out in June for reference and purge valve went in in July/August and never had an issue.
