Van started idling high last week. Had it scanned by mechanic and got 1504, and 1506. Was told to replace the IAC, and TPS and did so. Problem continued, and thought maybe the new IAC was defective so Iexchanged it. Still have the same problem. Had all the vacuum lines tested and they are all good. What else could it be. Also took the TB off and cleaned it.
