I don't understand this, maybe someone can explain...but the mechanic
said he took the vacuum off the EGR valve and the car isn't hesitating
anymore. Is it normal for the EGR valve to not be under vacuum? Does
this sound like the EGR valve itself being the problem, or the solenoid
that controls it? I know the EGR valve itself is like a $20 part, they
even change it for you at Jiffy Lube. Figures it looks like that silly
engine code may be the culprit after all, guess this is what happens if
you ignore a trouble code for 6 months.
