Got them at Costco because I’m dull.
But on the way home my car went into limp mode with a check engine light and a computer error light.
Called Costco and they said “we just did the tires” but when I reset the system by disconnecting the battery the traction control, power steering, and tire pressure lights came on.
And it’s still in limp mode.
Taking her to my guy later today.
Thanks Costco.
ETA: Turns out my coil packs and spark plugs went bad, it was just a coincidence that it happened after the tires.
ETA II: My guy said the spark plugs were all the wrong kind.
Costco is pretty far from my house, so that was a major factor when we decided it wasn’t worth making that trip once a month.
I only ever use them via Instacart and for tires. Though maybe not even that anymore.
