Hey all,
Dumb question I know. Here's the gist.
This past summer my Pro5 was idling very rough and achieving a miserable 450Km per tank instead of my usual 550.
I had the plugs and wires replaced ahead of schedule. It was the best my garage could figure that was wrong. This garage is owned by family so there's no concern about them.
That didn't fix the problem. I took it to a mazda dealership that said they couldn't figure out what was wrong but they said it could be the aftermarket plugs. They said they don't fit right.
I figured that was just a cop out and BS.
Recently my check engine light came on and the symptoms got worse.
Thankfully though an actual error code!
Random/Multiple misfire.
I tried new plugs(a different kind this time) and new mazda coils. The problem isn't fixed. My garage couldn't figure it out. They even removed the timing belt cover(is that right?) to see if its possible it slipped and the timing was off. My garage hasn't charged me a nickel yet. They said they'll worry about that once we solve the problem.
They told me to take it to the Mazda dealership and have them diagnose it.
My appointment is tomorrow(Monday). I fear they are going to blame it on my aftermarket plugs and/or wires again.
Is there any validity to their claim that aftermarket plugs could be the cause? All common sense to me says no, but I'm seeking the advice of the Mazda forums.
If its not the cause, what can I tell them if they tell me that again? I am just amazed that the Mazda dealership themselves couldn't figure out what was wrong with their own brand of car last time. My bet is the same will happen this time.
What also amazes me is the "trial and error" nature of automotive diagnostics and repair, all at my expense. I would think in this day and age they could pinpoint the exact problem and replace the part and voila!
Edit: Oh ya. I have 127,000 Km on the car. Its a manual Pro5. Maintained as per the owners manual to a tee by my garage. Even had the tranny fluid replace trying to figure this problem out.
