Hello I'm new to the fourms . Short story i had my exhaust manifolds replaced now i have a rough idle and five code p0106,p2195,p2197,p0171and p0174 . I'm just wondering if it can all be related to a bad egr baro sensor. From them heating it to get the egr line out?

I found this information when I GOOGLED your codes;
"Ford P0171 & P0174 Lean Codes. A Ford P0171 is a LEAN code for cylinder bank 1, and P0174 is a LEAN code for cylinder bank 2. These codes commonly occur on many Ford vehicles, and are set when the powertrain control module (PCM) sees the air/fuel mixture is running too lean (too much air, not enough fuel)."

"P106 is a MAP SENSOR."

"What the P2197 code means. This code is usually an indicator of an O2 (oxygen) sensor problem, although there are several things that can cause an O2 sensor to fail. The most common is a vacuum leak in the intake manifold on bank 2, in the case of this code."

From the information I'm reading here, you quite possibly have a vacuum leak and/or O2 SENSOR problems. I would get a VACUUM LINE SCHEMATIC/DIAGRAM and ELECTRICAL DIAGRAM for the O2 SENSORS and EGR. Follow those lines/wires and check for any burnt or broken wires and/or vacuum lines.

After a goodnights sleep and some day light so I could see ,I think I found the issue. The purge line was broken all i had on hand was a feul filter on used it to connect the 2 ends and it started idling fine. Took it for a short drive and check for codes no codes fingers crossed that is what it was. Just spent 1000 bucks having manifolds replaced.
