Asides from the miss firing is it using the same trans or a different one from the donor car?
so my old engine crapped out number 3 rod bearing so i bought a used engine, it has good compression looks pretty clean. but after the change it now has no power at the low end rpm's 1000 to 2500 then after seems o.k., has new plugs, wires, filter, it also seems to miss fire, do i need to reset any thing? or do any thing else?
No it won't make a difference if it's the same. There are different ring and pinion combos that would make it feel like you lost power.
Forced convection.... Now we grillin.
Some times she goes, some times she doesn't.... Way of the road

Check your vacuum(sp?) hoses. I had a similar issue with low end power on a 1.8T AWM engine. Ended up being the fuel pressure regulator vacuum line was ruptured. Caused misfires too and poor idle. Might not be the same line but I would definately check them out to be sure.
I have one other question my old engine had a egr valve and the new one does not will that make a difference at all .The new engine came with the wire harnessso i just twisted the old harness off at the conector and just plugged it into the car. do i stillneed to unplug #10 pin at the ecu.................
I'd say yes, then you know for sure. (regarding cutting the EGR wire)
I'd also take the distributor from your old engine and put it on the new one. I had similar issue with a bad "cam position" sensor. It's part of the distributor and can't be bought separately. Or check to make sure you have it plugged in. It hangs pretty much directly below the distributor. Will have to feel for it.. 3 wire plug.
