I have an 89 Volvo 740 GL non-turbo 8-valve sedan. Hard to start,\nbarely runs unless you give it a lot of gas.... when you put it in\ndrive it stalls right away. In neutral or park, it won't idle at all,\nyou have to hold some accelerator all the time, or it will stall. I\nread the stored codes out, it has set the code for bad air mass\nmeter/sensor. I also have a 92 Volvo 740 GL with the turbo engine.\nSame type/size, but has a turbo. I don't want to buy a new AMM for the\nbroke-down 740 sedan, and try it, only to find that there is something\nelse wrong like a bad connector. Usually these electrical parts are\nnon-returnable. So does someone know if the AMM in my 740 wagon is the\nsame AMM used in the 740 sedan? If they are interchangeable, then I\ncan try the one out of the wagon in the sedan to confirm the fix\nbefore buying a new one.\nI know these things have a delicate platinum element in them...is\nthis something that you shouldn't buy used from a junked car?
