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.
It has a custom exhaust and intake so I wouldn’t be surprised if the previous owner put in “performance” plugs which then wore out the coil pack.
I have my own Bluetooth code reader but funnily enough my mechanic had it because he put his reader on it and accidentally left it in the shop. So I picked it up when I got my car today.
