I don't think the issue is when the cel light comes on. The issue is that it wasn't coming on, before. Ya don't want to know, Ok.
Wait what? The old o2 wasn't coming on. The new o2 is coming on. The new o2 stops coming on when I turn the car off and jump start it. Sorry if I am being belligerent, I just feel like neither route will avail me, and I'm torn between stodgy know it all professionals and self empowered educated guessing amateurs. (That sounds mean, I don't mean it to be.) I am very appreciative of this forum. I think the sheer amount I post on here should be some testament to that. I'm just stressed out right now because the mechanic is such a douche. Given that, I do think he knows his stuff, given the sheer number of cars he's worked on and his experience. Anyway, sorry for coming across unappreciative. The other thing is, I just don't have much confidence in my self doing my own work on my car.
It's really weird how some VX's can use the $79 LAF sensor from Global-Automotive and some can't. Could it be that the Canadian ECU is set up differently than the 49 state ECU?
AND, it is always better if you are the mechanic. At least, you know who f***ed up and why!!!!! I wish "professional" mechanics had more training. I have had my share of headaches with them over the years.
I was thinking about this too (the first part). I really want to put my new ECU in and see if the o2 sensor will work better with the new ECU. Although I suppose there is no logic for why it would.
Well, it's really troublesome he cut the old o2 sensor up. I don't spose you like soldering? Hmmm... I would get the o2 sensor in there and swap the ecu and see if that does anything (I doubt it though) and then I would throw a **** fit at the people who sold you the o2 for your money back.
