[W126 Coupe] 560 IDLING PROBLEE

[CHRIS]

Gentlemen,

I have an 89 560 SEC that I am currently restoring. It runs well but
the car hunts at idle and will not
continue running without adding gas until it warms up. I noticed in
previous discussions that if the fuel
economy guage is fluctuating that there is a vacuum leak. We checked
all the lines under the hood and
there is no noticeable vacuum leak. Just looking for some additional
things to check. It's driving me nuts.
short trip. thanks, Chris VA Beach
