Recheck all your hose and electrical connections. Sounds like a vacuum leak.

Do a compression test on all the cylinders. If the exhaust is "sucking back in" that would be a dead exhaust valve but there would be alot more going on than the little you described.

might be as simple as a compromised O-2 sensor, did you use any sealers on the e-manifold instalation? many people also use antiseaze (debatable I know) for the studs and nuts, if it were to get into the manifold on instalation it might cause falure of the exhaust gas sensors
