boost problems ???

[zachallen19]

so my check engine light came on so i ran it and its the 02 sensor
but its overheating a bit over 190 where it should stay(which i wouldnt think would have anything to do with the sensor) when it heats up over 190 it wont build boost at all, i can let it cool down just a bit and it builds boost fine any one know anything about this
thanks

Nobody is going to be able to answer your question when you don't even list what kind of car it is! And you shouldn't run it while its overheating, especially not boosting it!!

could be head gasket, improper timing, running lean, too hot a plug, bad thermostat, bugs in your radiator, walmart bag on your radiator, low on coolant, bad fan switch, bad fan, no fan, no radiator, bad temp sensor, and last but not least bad mechanic.......
