302 V8 Engine code question
Hello
I have a e-150 V8 302. I Have been having a problem with hesitation when accelerating whether from a stop or at highway speed Idles fine otherwise.i checked the codes and they were 327 and 332. Now i am not sure the hesitation maybe tune up related but where should i begin with the egr codes. I want to avoid changing any unecessary parts...thanks for any help i do appreciate it greatly

Step #1 for me is to check for vacuum leaks and levels. Start at the EVR (egr vacuum regulator) and check for leaks coming from the feed (engine) side, then to the egr side. Levels should be around 14 on engine side and 7 to the egr I think.
Next check the operation of the egr itself, a cleaning may help. It should active the sensor when it opens with a small rod type thing (sorry about my poor technical terminology here) If the rod is moving but you still get those codes, replace the sensor.
