That's a good sign!
If the head gasket blows out directly between two cylinders, it is possible for there to be NO coolant leak, but, those to cylinders will have little or no compression and, therefore, will not fire
Let's hope that isn't the case here...
I don't know if it could be the 02 sensors or not. Generally, at this stage, I would expect that they would be throwing a code, which you should scan for, anyway, even if the Check Engine
Light is not lit up. There may be a pending code nonetheless.
You only need to replace the two upstream 02 sensors if you plan on replacing them, by the way.
This sounds like a cylinder, or cylinders, not firing to me.
You just need to find out why.
If you have a way to scan for codes, do that first. If not, do what I said in the earlier post so that you can figure out which cylinder is the problem.
