My cousin has a 1991 Q45, V8 with traction control. Her engine is hesitating on her, seems like it wants to quit. Local diagnostician told her it is problem with secondary throttle sensor. Dealer wants $700 for the piece. Junk yard would sell it for $100 but has none. Is there a substitute, or a way to fix the one she has? (She just spent $1700 on struts and tires and is kinda tapped out!)
We are in the LA area.
