okay i have a 2000 xj sport with the 4.0 and it runs great. BUT when it reaches 210 degrees and i turn it off and go to start it again it wont start right and it misfires badly and stalls on me but its fine unless it reaches that certain tempurature please help!!!!

 

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

 

so i got the heat wrap did it without a problem butwhen im offroading and it get to 210 it missfires horribly still

 

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

 

grab yer gun and take her out back.....its over
