alright so i just finished my engine swap a couple hours ago. it is running well but missing a little. it was running good before i screwed with the wiring (o2&MAF) so im assuming thats the reasoning for the maf code. the other code i am getting is a code 21 ignition signal, i am assuming this is the reason for the miss. i am going to recheck my maf wiring and see if that does it. any ideas what would cause a code 21 though? it wasnt throwing this code in the 180 that the engine came in.

Thanks,
Tyler
