So previously I have my my power train light come up on my my BT50's dash. Took to Mazda and had my Inter-cool pipe and MAF sensor replaced. Eleven months after the light popped back on after around an hour and a half of driving, drove home slow then turned car off, no further problems. Around four weeks after the light came back on after driving for an hour and a half. Took to mechanics and they can't seem to find a fault. I know this isn't normal so something has to be wrong but no one can tell me.

Yeah. We are going to have to ask them to clarify what they found. Was the check engine light on when you took it to them? If the light was on then there was a code that went along with it. However, if the light was not on and it was a bit of time since it had turned off then the code may have cleared itself.

Some codes are known as two trip failures. This means it takes the failure to occur two times for the light to turn on. Most of these same codes will also clear themselves when they don't see the issue x number of times. Normally it is between 2-5 times of no issue and the light will go off.

Here are a couple guides that will help with this. Let us know if the light was off when you went in and then does this only stall after driving for 1.5 hours?
