look what the dealer told me please help
In any case, any moron with a Tech II can see that something went wrong by simply scanning the PCM. Why do they need to try to reproduce it? It already happened and is stored in the PCM...what more proof do they need...a malfunction is a malfunction whether it happens at 0 mph or 100 mph.
Go show them the problem is still there...since GM made a car capable of going 123 mph, it should be able to do so without malfunctioning. It doesn't matter if they don't want to drive that fast...the bottom line is, there is a code stored in the PCM showing a malfunctioning O2 sensor. When something breaks under warranty, GM needs to fix it. Period. If that dealer won't do it, call GM Customer Service or try another dealer.
They are lying to you, plain and simple. Tell them to replace the O2 sensor. If they give you too much ****, go over the manager's head. If you get shut down, just replace it yourself. Yeah, it sucks, but I've had too many dealings with dealership dumbasses to trust them ever again. I'll do my own work, thank you very much.
