p0108 map sensor problem and more
 

Hey I could really use some help so I'll start from the beginning.About two weeks ago my 99 honda civic ex would jerk then stall whenever I came to a stop, then the battery light came on, I replaced the battery and still no success. My mechanic friend said it was the alternator that had gone bad so I replaced it with an after market one along with the spark plugs because they were old as well, still stalling. I got an obd2 scanner and kept getting the code p0108 for a map sensor. So I went out and got a new one. When I put it in the car ran perfect, for about an hour. I came out three hours later to start it and it would turn on but the engine won't turn over. If I unplug the new map sensor it will turn over but all the low idle and stalling issues come back
