Thanks marc-o-matic, it is a 1988 3800 V6. It is not under throttle body. When you say "lower right corner of engine block" I assume drivers side, firewall side. I will look there tonight after work, I remember the exhaust and some tranny lines, etc. being back there, so hopefully will find it. Would it be best to look from underneath - or from the top?? Thanks again - I truly appreciate this. kurt
