Replaced water pump car makes weird noise

Recently I replaced water pump on 00 Infinity I30 3.0 by my self. End up taking off the intake manifold as well to check to see the condition inside. Noticed it was full of oil; washed by putting fuel inside and had it flushed, after when I finished cleaning I installed the intake manifold back and instead of replacing the intake manifold seal I put the sealant instead.
Now this cars have a chain where the ADV IGN should be at? what degree, on my scanner it showed ADV IGN 5 degrees and I have other vehicles at the house I noticed that they are 5 degree higher. My engine runs rough now; it wont accelerate same way when I test drove my car. If I try to hold the rpm at about 3 rpm it wont stay it starts to go up and down. But if I just push the pedal once the rpm go up and down just fine as long as I don't hold it steady. The ECU starting to show few DTC's p1165 and p1130. Trying to figure out what I did wrong. Is it possible that when I put the water pump back I some how messed up the ignition timing? or is it because of the sealant that I put in and now it has restrictions? And I noticed that the engine is getting hotter now because fans come more often now then before installing the water pump.
