We took in my Mazda rx8 2005 to the shop because it had trouble combusting, cause we could smell strong fuel odor. I took it on Thursday went to go pick up my car on Friday and they told me that two spark plugs had to be replaced. Took it home was running fine, went to work was still working fine, but the next day on Saturday morning tried to start up again and was having trouble staying on and my engine light kept flashing??? Called the shop and they told me they will see wat they can do on Monday?? Wth, so i hope i dont get charge for more towing and the crap that they didnt fix. Any suggestion out there what might be wrong now if the mechanics said it was only two spark plugs, but now what wrong??? Help, I also still have warranty on the car so hopefully if its something big my warranty can cover it
