Working on my 96 k1500 with the l31. Blew an oil cooler line and locked up my old engine so got a cheap replacement from a 97 tahoe to hold me over until i get my ls3 built. Fired right up has a nast exhaust leak after the cats( picked up a new gasket that ill replace tomorrow) i put all my old stuff on the used motor aside from the cap/rotor, knock sensor and crank sensor. Ill be checking for vacuum leaks in the morning and swapping out for my old cap and rotor. The truck isnt smoking but seems to be running only on a few cylinders. The new motor came with the updated fuel injector also. Im getting the map code p0106 could it be lower intake gaskets or possibly a burt valve or something in the valve train. My old motor ran like a champ so just a little stumped by what it could be. The guy i bought the motor from said he ran it and it sounded fine but it was after he already pulled the y pipe. Thank you in advance
