I'm having a hard time getting my EGR and vacuum problem resolved on my 94 SC.
I originally had a few EGR codes. I replaced the EGR transducer, and the EGR vacuum solenoid. This took care of all of the codes except for 332 insufficent egr flow. I then replaced the EGR valve itself. The code 332 is still there.
I seem to also have a vacuum leak. The gage reads about 12 at idle and drops to 0 as soon as the car is shut off. As soon as you get above a few pounds of boost the car bucks, for lack of a better word.
Is it possible that due to the leak there is not enough vacuum to open the EGR valve?
Thanks,
Joe
