I have a Luminar 90 and had a stall problem two month ago, and found useful information here. I finally cleaned AIC myself and put back again, the car runs good after that.
However, another small start problem come out. Recently, after one night sitting, the car won't start once. First the car turn over, then I turn the key back and start again, it will start and runs good. Every morning this happens. It must crank twice and then start. During the day and short time sitting, no problem on first start.
Another problem is engine oil leaking. It has already been two years. It had been checked and said main valve seal is leaking. I tried several Engine Oil Stop Leaking, still can not stop it. So just add oil over a while. I don't want spend ~300 $ to haul the engine up and fixed leaking because I am afraid more problem comes up.
The car is old, but still run strong. I hope I can still keep it if I can fix these small problems. Any information about start problem and suggestion for stopping leaking are welcomed.
