Still having problems. Changed DIC a few thousand miles ago. Then developed an idle hestitation every now and then. Plus low Boost and low gas mileage (18-19mpg on SID). Went with reccomendations from people on the site checked all the vacuum lines and changed out the Mass Airflow Sensor. Boost problem seems to be gone. Gas mileage still seems to be a problem now at 21-22 mpg on the SID. Still have the idle hesitation every now and then. On a side note I checked the plugs prior to the Mass Airflow change and they looked to be a rich mixture. I have now ordered two new O2 sensors (Bosch universals). Am I heading down the right path on this or does anyone have any other ideas? Thanks in advance.
