Hi all, wow it's been a while since I was on here, good to see you're all around
About 2 years ago, I purchased the midpipe and headers from here (from Brian) and had them installed. Purrrring beautifully. About 15 or so months ago my engine light came on. Took it back to Mazda, they told me the front oxygen sensor was stuffed and needed a new one. As my car was under warranty then they replaced it for free and it fixed the problem. All hunky dory (Aussie terminology
) from then on.
About 4 weeks ago, the engine light comes on again. Thinking it was the same thing (stuffed oxygen sensor), I take it back to Mazda and they plug it in their computer and it says that the front oxygen sensor again is not responding. Something about it not heating up/warming up at all. I replaced the sensor again with another new one as per Mazda's recommendation, only thing is, engine light is still on.
They are now telling me that the only possible thing it could be if not the oxygen sensor (which is new) is the PCM (aka the computer). They believe that if this is replaced with a new or used one from a wrecked NC then it will definately fix the engine light/sensor issue as that's the last step in the process of elimination. (First the sensor and 2nd the computer).
The computer brand new from Mazda costs AUD$3900 and from a wrecker I can get it for AUD$1750, still a lot of money.
I don't really have a choice here because I can't drive forever with the engine light on, naturally it's sucking in more fuel and not running as good as it should. Before I spend this money, can anyone offer some advice as to A) whether this will actually fix the issue or B) what could be causing it?
Mazda seem to believe that it is because I have modified the exhaust system (which is BS in my opinion). Any help would be greatly appreciated from you knowledgable buffs!
