Mitsubishi Repair: 1995 Mitsubishi Eclipse, throttle position sensor, mitsubishi eclipse

Question
Ma'am,
 My daughter has a 1995 Mitsubishi Eclipse RS with a 5-speed manual transmission.  She tells me that the car dies everytime she has to come to a stop.  She also tells me early on; it would only die periodically, but now it is literally every time she has to stop.  The car will immediate start again, but the next time she has to stop; the engine stalls.  I have had the Idle Speed Sensor replaced in this vehicle 3 times over the past 12 months.  I would appreciate your advice and assistance.

Very Respectfully
George

George: You need to get your daughter's car coded. AutoZone would do this for free, it would rule out any other problems with sensors or the computer. You said you replaced the idle speed sensor, if one sensor is bad or weak. Sure shot that more are getting that way. Might look into a problem with the Throttle Position Sensor (TPS) the computer reads this sensor and then sets up the amount of fuel that it will give the engine. But again this only a idea on my part, the reason for coding the car. Would show up any problem with any of the sensors or the computer. The reason I ask you to do this, is because Mitsubishi farmed out the building of their computers to another company that did not build very good ones. With time a piece can start to leak inside the computer and then it will kill off the computer. Sometimes this leaking shows up with just the same thing that is happening to your daughter's car. But yet it could be that her fuel pump is not putting out enough fuel too. As soon as she starts to slow down for that stop, the fuel pump does not put out enough pressure and the engine dies. Does she run the car down to "E" before filling it. And hey with the cost of fuel I sure can understand that. But did she know that the fuel is what cools the fuel pump and so if she does that enough; with time you burn out the fuel pump. But you can have a test taken to make sure the pump is doing it's job. Oh if you have that test, make sure they do two tests at different times. Just the other day I was working on a GMC pick-up a 88, the pump put out the right amount of fuel most of the time but then I finely caught it when it wasn't. So replaced the fuel pump and the truck is running just fine now. Ok, now that was off the top of my head, now my repair manual... it's ideas.. fuel filter clogged, distributor cap damp or damaged(so when was the last time you did a tune up?), faulty emissions system components (sensors or the computer), faulty or incorrectly gapped spark plugs(again part of a tune up) and then vacuum leak. It could be a vacuum leak too but those are often hard to find but it can be done. The reason I said at the start of all this was to have the car coded, it would rule out any problem with weak sensors or the computer. Then you could go to the other things I have talked about. I know this is long, but still give you some ideas to check. I mean the week-end is coming up, just the time to check this out for your daughter. lol. I do hope this helps and good luck! Linda :o)
(George:
 If you go to Sears buy a voltmeter, get a repair manual for that car, you could check those sensors yourself useing that voltmeter and the repair manual as it will explain the readings you need to be getting. Other wise try other shops you might find one that could hook the car up to their computer to see what it kicks back at them. But then it will cost you some money to do that. Still it would give you an idea if you did not want to do that work with the voltmeter and the repair manual. If you need anymore help, please write again. Take care now: Linda :o))
