Buddy has some gm o2s that sat in his car for 1 and half years with no use.They got mabye 3000km on them.He blew his engine with his ati and just parked it.Lately he said they weren't reading right at idle on his new motor and was going to throw them out.Should I buy them for like twenty bucks?
Do they go bad from sitting that long? Can you clean them off thought read propane torch works ok on them.What about solvent ,gas ,etc..???
These things are crazy expensive new so was thinking of at least trying them.My car sometimes dogs it off idle and sure the o2 are original ,car has 60,000 miles approx on it.
What do you guys think..?

NO to all of the above.They are about $65.00 each.
