[Shotimes] Aggrevating engine problem

[Paul Nimz]

My problem was a loose EGR valve.  It is more than likely a loose bolt,
broken or missing hose or cracked piece of plastic.  Get some Gumout carb
spray and while the motor is running spray the stuff around all the
potential areas for a leak.  When you hit one the idle will change
noticeably.
