Angry P1602 & P1571

Working on fixing up a 2000 Bonne SLE but now have some issues that are baffling me.

I get these two codes:
P1602 & P1571

I already checked and replaced the weather seal on the EBCM plugs, checked wires, resealed air box (as the factor ones where toast)

There were more codes before I redid the top end (LIM, UIM, plugs, wires, heads, ect). Some one before I bought it re-used the head bolts and even put in the plastic LIM gaskets again. But those codes are now gone.

Only get these codes when I put it into gear.

Things that are going to get done in the next day or two:
Solid front trany mount
TPS (found it faulty when WOT or quick peddle, on slow peddle its fine til about 3000 to 4000 RPM)
Fuel Filter (and maybe line to the tank if I cannot get the rust free)
maybe FPR (I have to test some more before doing this)

I will note that when I have the AC running the codes seem to show up faster then when the AC is off. These are the days I wished I had a Tech II

Well so far I haven't been able to get the codes to pop again yet. Replaced the water seals (the rubber gaskets) in the plug ups for the EBCM and so far that and resealing the air box where they sit seems to help for now. Will post an update if and when these codes pop or not again
