Ok, I bought a 1998 Grand Prix motor with only 58,000 miles to put in my 2000 Bonneville, I would just like to know if anybody has any information of common problems or procedures that I should be awar of to transplant this older motor into my Bonnie. I know about the motor mounts, oil pan, oil filter bracket, dip tube, what I don't know is about the sensors and or wiring, throttle position senser, etc. Any specific information or diagrams would be appreciated. I just want to get as right as possible before turning that key. Thanks for all you folks help. When It gets running again i will keep everybody posted..
