Heat Soak on the Fuel injectors. You need to add some heat sheilding around the injectors.

x2 heat soak boils the gas pretty much and it doesnt ignite right. get some of that heat shielding from jegs and wrap them up good

No check engine Light? 210 is normal operating temp. Start looking for vac or intake air leaks. Also check all the emisions sensors and the cat.

Might want to replace the temperature sensor. It is the one in the thermostat housing.

its sets no check engine light, i have already put a new temp sensor in the jeep already all 3 cats are fine and everything else seems to be on the up and up idk what to do for it anymore im running out of ideas
