Can you put a 2003 northstar engine in a 2002 cadillac deville?
I have a misfire code and they are saying that it has some head problems in the car. I changed the starter and the car started running like it had some bad spark plugs so I changed them out, replaced some vacuum lines and put some seals on the injectors. I still smell gas like it's not burning correctly it's loud smelling.
I will get a mechanic to do it. Do you have to do a lot to make it possible?
