Question about Chevrolet Monte Carlo
Sounds like a fuel injector that is failing when hot, this will definitely cause a misfire. I am assuming this is a late model car as you never said what year it is.
Here: while cold Ohm test all the fuel injectors they should all be about the same, about 14ohms -16 ohms
then drive it until it acts up then quickly while it's still hot do the injector test again and look to see if any injectors are signatively higher or lower in readings. Most often you will see the reading lower which means a bad injector, Change the bad one with a new Factory part and clean the rest by sending them out to a ultra sonic cleaning facility (most good parts stores with a machine shop can do this service for you) send them out that is.
