Back in April 2024, I had to take the car to the dealership bc of a check engine light came on. They said at that time sparks plug and some other stuff right. So to fix the issues it had at that moment 2k. I paid and it was fixed. Fast forward 4 months later car is running fine no issues but the check light engine comes on again. I took it to speedy to see if it was something not major they could fix. They said the spark plugs were backfiring to which I let him know that was already fixed...
