Question about 2000 Mazda MPV
I have a 2000 Mazda MPV DX that was running fine until one day, a spark plug started to malfunction. After replacing the fouled plug (yes, i should have replaced them all, but only had money for one!), it ran OK for a few days, then another plug fouled out, and by the time I was able to change all of the plugs, the car had started acting like it was misfireing on all cyclinders and sounding gerenally like ****. It was actually sounded like it was misfiring through the motor.
I had all 6 plugs replaced and after this, I had to make an emergency trip 3 hours one way, 3 hours back. it was still running like ****, but made it there and back. When we cut the car off after returning home and it cooled off, i got in it to go to the store and OH MY...it sounded like a shotgun going off under the hood, almost as if the spark plug wires were crossed/bare/touching. We limped it home from the store and immeditaely had it towed to a mecahnic who then replaced the air nodule, coil pack, all new wires and plugs (even though I had just put 6 newe ones in, I decided to replace them all again with the wires).
That didn't correct the problem, it was still sounding like it jumped time or something. The mechanic checked the timing chain, and nothing was wrong with it and he believes that it is something electrical going on, however, he is not experienced with the electrical components and his friend looked at it and they are stumped.
Could the computer brain cause this to happen? It's no longer showing any electrical codes, but it is still misfiring from what sounds like the motor under the hood. I am broke, so I am trying to figure out what may be wrong wtih this vehicle so I can fix it myself or have a friend do the work.
If your computer malfunctions, it goes into what is called a "limp-home mode." The mixture goes full rich and fouls the plugs within minutes. You are gonna have to find a GOOD shop that can properly diagnose the computer. It can only be done on the car with proper equipment. A bad ignition module can cause this too. Advance Auto Parts, Auto Zone and NAPA will test it for free if you take the module out and bring it in.
