internet says code is related to brake booster servo....so.....there could be a vacum leak somewhere, messing with your brake booster and also map sensor readings and inturn your ecu. redneck solution to find a vac leak is spray brake cleaner (flamible stuff) around your engine bay with the engine on and see if revs increase when you spray it in one area. ________________________________________ the world is changed by people in sheds |
