The car seems to be running fine, not rough at all. I didnt check the gap on the plugs, just took them out of the box and put them in. What should the gap be set at? I ordered a new coil, it will be here on monday,,,,I dont think that is it, its more for piece of mind.

What other things should I try? I read somewhere about having to do a "relearn" on the ECM after doing an engine swap?
