so not only did we argue about how many O2 sensors I really had I pretty much got no useful feedback from anyone on this forum...

and there is a way to change from the Calif emissions to non-calif emissions...

The value of that data is a wash. You've got the magic software program so you shouldn't need us anyway............LOL

I am sitting here looking at generic OBD2 data and nothing really stands out as an indication that something is wrong. Looks like two snap shots were taken at idle with the engine warming up.

You stated the problem your having occurs at when the engine is under load. Your not going to get too much from the OBD2 side if there is a misfire going on. Can't really tell from the vacuum leak you created if the O2 sensor responds or not because we are only seeing one frame of data.


Oops thread got locked...just noticed.Unsure





Since we volunteer our time and knowledge, we ask for you to please follow up when a problem is resolved.

I pretty much got no useful feedback from anyone on this forum...

I don't think that is a fair statement at all...... Taking my posts out the picture cuz I'll grant there isn't alot of useful info there, I've gone back thru this thread and see a lot of useful info from the other mods... These guys donate their time and knowledge for free and to come in here and say that is bs. You started this thread completely wrong....Rather than stating the problem you had in the 1st post, up front, you start asking about a system that is going to have nothing to do with the driveability problem you are having.... You come in later and spring that little nugget of info on us. So yea that turned what could've been straight forward problem and answer thread into this twisted mess..... Once again, I'm not talking about myself but you have no clue who you are insulting............
