2003 mazda protege5 recently started dying when i am driving in the city My 2003 mazda protege5 recently started dying when i am driving in the city. On the highway it's fine. When it dies, it drains the battery also and requires a jump , but will only run for about 10 minutes or so then dies again. I figured it was an electrical problem but when inspected and tested the alternator, battery and fuses all checked out. Ive taken it to 2 mechanics already and they can't seem to figure out what the problem is. From what I gathered from the interweb it might be the fuel injector or maybe even the electronic module where the spark plug wires connect to. I need to know for sure before I take it in for repairs, I've been ripped off before.

The engine and transmission in this cars drivetrain is fully electronically controlled by a computer called the PCM (Powertrain Control Module). Whenever a problem like this occurs the computer stores a record of the problem in the form of a fault code in its memory, to read these fault codes you must have the systems memory scanned with a special tool. Once the fault code(s) are read you then must perform the appropriate diagnostic testing to find and resolve the problem(s)
