Hi , I had a problem with my toyota corolla conquest 2002 couple of weeks ago, the car was driving with less power, and using lots of petrol. I took it to a mechanic, he changed the coil (#4 I think it was) and everything was fine. Until, this morning, where the car would start and then turn off straight after, tried few times, and it cuts off by itself within 3 seconds of starting. The road side assistance said it is showing error P1315 on the computer, after half an hour of trying the car just started again, and everything was fine. I don't know what the problem is! and should I take it to a mechanic to have a look at? Will the problem happen again?! Thanks, Pete.
