2001 BMW 330i Question: How much will it be to replace the head gasket at any common mechanic shop?
sounds like you need to get a proper diagnosis.First try to retrieve the trouble codes,if any that are set.does it overheat? are you low on coolant? the symptom you described sounds kinda like a vacuum leak. - bmdouble
This needs alot of diagnositics. The problem could be a lean condition to a idle air solenoid,head gasket problems has with it other conditions. - Spring Branch Imports
agree w #1 and #2 get proper diag. the head gasket job will be expensive. appox 2000.00 to 3000.00 so a diag fee is cheap - globalhelper
