I need some help with this one. I only get code 32 after the A/C is on. It never comes on when the A/C is off. It also only happens some of the time. Does anyone why this could happen (isn't 32 the EGR?)

thanks

 

You may have a small vacuume leak that only affects the EGR operation when there is an extra load placed on the engine such as with the AC engaged.
Also have you replaced the cam with one that causes a lower than normal vacuume signal? Not sure if this would cause the prob you describe but is worth checking out. EGR system needs about 10 inches of vacuume to operate correctly BTW.
