    Hey guys, first off-I am NOT a mechanic but thought I would pass along some stuff that I discovered on my 355gts (96) that might help someone else: was having idle issues..basically it was hunting all the time at stoplights. after alot of $ and time discovered that connection to the front and back O2 sensors were swaped during the 30k reinstall. Switching them back seemed to solve the problem. will keep you posted though. Also, was having temperature issues (car was running hot) turned out to be plugged hose to the coolant reservoir. Worth mentioning that if you have the same idle problem and it's not something hair brained like o2 sensors plugged into the wrong spot...the mechanic said that it is normally a vacuum leak somewhere in the system (?-not a mechanic so I guess someone knows if that's b.s. or not). I love the site and really appreciate how we are all here helping each other out with these kinds of things and thought I would try to do my part. Thanks for all the help I've received from other people's posts and happy motoring!

    ...vern, no..no cel's...but that was because (apparently) the bulbs had been removed by previous owner.

    Not BS. Hunting idle could easily be a vacuum leak, glad yours wasn't.:)
