Absolutely terrible experience with Toyota of Rich...

Absolutely terrible experience with Toyota of Richardson. Bought a certified pre-owned vehicle from them November 2017. Nearly two years later my Tacoma has been in the dealership for 64 days after a check engine light came on. First they said it was the compression in cylinder 1 and they said they fixed it. I picked it up and the vehicle stalled on me while driving it home. They towed it back. Now they're saying it is the O2 sensor so they said they fixed that, although the mechanic told me over the phone that every time they shook a wiring harness it killed the engine. No one at Toyota of Richardson wants to acknowledge its an electrical issue and that they sold me a lemon.
