I see post after post regarding problems with these aftermarket Opti manufacturers/sources, and still people will go out and keep buying them. Even after telling people that I've seen dozens of problems with some of these POS parts, someone will respond "my buddy has been running one for two years with no problems", and the guy who asked for advice will run right out and buy one of the POS parts.... totally ignoring input that says "over the past 10 years, I've seen nothing but problems reported".

 

Good grief the opti was changed prior to June then in June it threw codes. Changed it again in June. Then in November changes it again and it's throwing codes after changing it. Something is screwy here. You been using these every time?
