Yes,it is quite common on the Northstar engine, usually due to lack of cooling system maintenance.

The most common overheating problem with the Northstar engine is a blocked purge line(small hose).The purge line is designed to purge air out of the cooling system.
There is a small diameter hose coming from near the top of the coolant tank (not the cap) ,this is the purge line.
With the engine idling,pull the purge line from the tank,if there is no coolant flow from this small hose,it is blocked and this will cause overheating.
If the hose is clear, check for blockage at the nipple on the tank.Or trace the hose back until you find the blockage.
The hose goes in to the engine to a crossover and comes out the other side close to the thermostat housing,the blockage may be there.

Recently bought XJS V12 with 15K miles; driven only 1K miles since 1993. I drove the car 250 miles the day I bought it with no problems. Since then, it idles well for 30-60 seconds but then stalls.


Check the fuel filter(s). Your long drive may have shaken dirt or old fuel gunk ("varnish") loose and plugged the filter most of the way. Enough fuel gets by to start the engine, but then it starves when you put it under load.

When something in the car's faulty and a sensor picks it up and tells the computer, the computer will cause the car to do exactly that. Could be anything, from a damaged air intake sensor to the breaks.

Have your car connected to a computer and let the computer do the talking for you.
