I recently failed an emissions test and 3 shops told me its either o2 sensors or the cat. After a diagnostics by Lextechs, they discovered it was a rusted Y connector. Translation: was looking at $1,600 in repairs that ended up costing less than $300. At the same time I had a long standing issue(cv axle boot) fixed while in their shop and both jobs were done quickly. Only reason its not 5/5 stars is that now my wheels squeak the whole time I'm driving. Not sure the cause, just know it was not doing this before repairs. Passed emissions and have a working car. Thank you for honest service!
