A friend of mine has a 90 model I think, and his jeep is having problems so I am looking to the experts here in order to help him.... It will idle fine for as long as you want... You can drive it for about 15 minutes before it boggs down and feels like its going to die... If you turn it off for about 5 minutes, you can drive it again for 15... He says that he has eliminated the exhaust as an issue ( i thought clogged cat), and says he has traced out all of his vacc lines...

anybody had this issue before or close? any ideas??

thanks a million!!

 

map sensor could be bad if its not a clogged cat has he checked to see if debri might have gotten in the intake air tube or throttle body is he sure the cat isnt bad have him unbolt the exhaust at the manifold try driving like that and see if it still does it if not than its a bad cat

 

Thank you for your quick reply!! He states that he has already checked all of these... Any other ideas out there??
