Hey guys, just picked up this super nice 560. Cool story bought it from catholic nuns who received it from the original owner the former CEO of Burlington Northern Railroad. Very well maintained all books and records came with the car.
The only problem is some stumbling at idle and occasionally it will stop running, but restart.
I have been searching the forums and looking at the usual suspects but haven't solved the issue yet.
I ordered a new OVP relay as the one in it looked original and was getting warm.
I have looked pretty hard for a vacuum leak but nothing yet.
I did read that there were some issues with rusted fuel lines that can cause some similar issues but not sure on that one.
Symptoms car starts pretty quickly seems good for a few minutes then the idle gets a bit rough not terrible but noticeable.
Driving the car can feel fine at times but intermittently bad, if you try and give it the goods it stumbles then engine revs but doesn't feel right and hesitates to down shift.
What do you think?
