So, my el cheapo '84 300D has become a hot commodity for our 21 yr old daughter who recently had her parked Volvo 7-series totalled by an inattentive driver down in San Diego. This car has been driven almost daily by my wife, but has been severely neglected by me, due to its unfortunate penchant for utter reliability, and my disdain for working on the 123 chassis. I know it needs lots of front end work, 'cause it chews through tires at an alarming rate (inners wear really quickly). And, the doorlocks and IP shutoff are slow to respond, if at all.
My daughter is flying up on the 2nd, so I have very little time to diagnose and treat. Are there any readily available reference materials out there for fixing a vacuum leak in the door/shutoff circuit? Any obvious leakage points I should address first and foremost? I recently replaced the driver's door vacuum switch. TIA
