This is so common & usually it's the mechanic not diagnosing the problem correctly.
The problem usually involves oxygen sensors. For example, the code says something like "mixture rich bank 2", so the mechanic straight away blames the oxy sensor & the owner is needlessly out of pocket.
What they don't think of is. why is bank 2 rich? Did the oxy sensor cause the issue ? Probably not !! The oxy sensor is telling what is wrong & yet you are "shooting the messenger".
I probably sell more EFI sensors of any type than anyone else in Sydney (or maybe Australia) & most/many mechanics just don't diagnose correctly. Many treat their scanner as a 'money making machine', where they just do what the scanner says & often the owner goes along with it, depending how good the 'spin' is.
So you've got 3 types of mechanics. Those who don't know what they're doing, those who do not what they're doing & treat the customer as a 'cash cow' & finally those who know what they're doing & treat the customer (& their car) with some respect. Sadly the last lot are in the minority
