Ive been noticing a few problems with my Vx lately.
First was mpg has lessened, but mostly the start / stalling
problem. This can happen when cold, but sometimes more
so when warm.
Start...then dies.
An easy way to see if your regulator is bad is to simply pull
off the vacuum line. If it smells like gas or gas literally pours
out of the hose, your regulator is toast.
Try BAP before the dealer to find one new if you can.
I didnt find changing it all that hard, but took about an hour.
If the problem was there too long, it could of actually washed
the cylinder walls of oil with the extra fuel being sucked in.
Pull your dipstick and smell your oil. If it smells like fuel, I suggest
putting a qt of ATF in the oil, start and let idle for 5-10 min, then
immediatly change your oil and filter
