Have it scanned to see what is happening!
Thanks, I knew that much was hoping for a little more info.
You mean a best guess!! Information is gathered during diagnostics! Fuel pressure regulator is defective, there's my guess!
Thank you again, I wanted an educated guess, yes, but I am taking it for diagnostics next week.
Smart move!
