hey guys I need some help, I just put a used 3.0 engine in my 88 SE-V6 and it starts very well; yet, the idle is bad. It will idle at about 1700rpm then surge to 3000rpm. This will continue indefinately. I wonder if I screwed up with the vacum lines or something. Thanks for any help.

Check all your electrical connections, make sure there all hooked up including your oxygen sensor. These engines are totally dependant on signals recieved from all it's sensors to run right. One wire unplugged could cause all this. Also check the computer for trouble codes, this will tell you if a part is malfunctioning or unhooked. Good luck
