Hey guys, my check engine light has been on my celica since it's been rebuilt (salvage title, twice). The computer said it was Oxygen sensor, so I changed both. The check engine light went off for 1 day (yesterday), and it came back on today (this morning). The guy who rebuilt it put green engine coolant in it, do you think that could be why? I'm just trying to figure out why it came back on. If you have any ideas, just let me know.
If you want to email me, it's :
