I replaced the thermostat with no problems. A little tight working area but all in all not too bad. Thanks for the advice. Now it's throwing two codes. PO171 and PO174. Bank 1 and 2 are lean. Would that indicate a vacuum leak? Is there anything obvious to look for or perhaps re-do my assembly proceedure? Thanks for any ideas you may offer. Jim:angry:
