UPDATE: I now have the car at a supposedly reliable Mercedes-Jaguar-BMW garage here in Las Vegas. It came recommended to me from a friend of mine. So far, they replaced an O2 sensor that was supposedly bad. . .the Check Engine light had been on and they said replacing it would fix it. Also, they checked out the fuel distribution system and some other things under the hood. I asked them if they thought it was a fuel filter or fuel pump problem. They said no, saying that the filter had been checked and the fuel pumps had given regular voltage readings. So, they concentrated on the above mentioned things. Now, today. . .Wednesday. . .they tell me that the other things they fixed did not change the cars stalling/missing. They are now looking at the fuel pumps and telling me that the pumps appear to be "used". . .as if somebody else had replaced the originals with used parts, saying they look as if they had been "painted." Who knows. . .but has anyone ever heard of this? As a side note, on Monday night before I dropped off the car at the garage, I noticed that at the back of the car a very audible whirring noise that I had not heard before. How loud are fuel pumps on this car supposed to be? I'm beginning to think this is something really simple that these guys are missing. . .like a vacuum line or a corroded ground wire dealing with the pumps or something in the fuel system. Also, the car revs fine in neutral. . .only when it is pulling a load does it miss. What's the life for a fuel pump on this car? The car also has rotted motor mounts that need fixed. . .this car must have sat quite a bit.
