Im assuming I need to replace my 02 sensor cause I keep throwing the PO134 code, my cars running $h!tty, and its sucking down gas like I can afford it.

So taking into consideration what I want to do w/ my car in the future, I decided to go w/ the PLX because I can replace my bad sensor and also monitor the A/F.

I guess Im just looking for a sort of product review on the M-300 specifically and want to know what people like/dislike about it and whether or not you'd recommend me buying it.

 

I use it in my car and we have used it in numerous shop cars and customers cars. It's a very great reliable unit.

It also uses the cheap $50 bosch sensor, so if you ever need to replace it it won't cost you an arm and a leg.
