Problems with engine swap
Hey there guys, my name is keith and im from illinois. I picked up a 2006 jeep commander about 2 years ago. Recently the the engine blew leaving me with a rod through the block and lost hope. I finally found an engine for my 3.7 and swapped it in a matter of days with alot of spare time. I tried starting it yesterday and the only thing that happened was the horn woke up the neighborhood and threw two codes at me. Help would be appreciated. Also more info the engine i planted into it is now a 04 jeep liberty 3.7.
