I've had my (2004) car for a few months now and other than a sticky fuel gauge and CD changer, everything runs great and I love it. I'm the third owner and I trust the previous owner to have taken care of it, she currently has 93,242 km (57,938 miles for my American brothers)

The issue was this. It had been running like a dream this whole time, then I took it out for a short trip after 3 days in the garage, and all of a sudden she was fighting me on any sudden acceleration or when I put any kind of load on the engine, especially around 3-4k rpm. It felt like it was hiccupping or something. I figure its misfires in the engine as such I pulled out the ignition coils, cables and sparkplugs. The sparkplugs were pretty dirty, and one of the top ones was very corroded at the contact with the cable (green/brown). The ignition coils were in similar shape with all but one having significant white dots. I have no idea when the previous owner may have changed them.

My questions are threefold

1. Could I be misdiagnosing the problem? What other things should I check/replace to rectify the issue

2. Are these suitable replacements? MAZMART - Serving The Mazda Community Since 1980. Wishlist

3. Could anyone point me towards a European/Swiss retailer to save on shipping costs? My cheapest option is around 60 Euro

Thanks in advance for the help

 

That is a suitable set for your car. Definitely replace the ignition. You are starting in the right place.

I can't help you with overseas vendors, being a Yank.
