Ive got a 99 Xplorer 300 and Ive tried to adjust the carb but didnt help much. When it starts to cut out you can choke it and it will take off agian for a little bit until it start cutting out agian or boggin down. Its new gas and i put treatment in it. Also new spark plug. Also I thaught somethin might of got wet so i put it in heated garage to dry over night and nothin changed. And it seem to do it alot worse in reverse than going forward. Any ideas or tips would be much appreciated thanks

 

does it act like the override is cutting it out?

 

i dont know about with the xplorer but with the trailblazers u can pull the front hood off and unplug the override switch and i did this and it did kinda the same thing ur describing so check and see if theres anything thats not pluged in completly tight ot not at all

 

Well it does it going forward also. But seems to be worse in reverse and sometimes i can get it goin in reverse with the overide button not pushed in. still sounds like crap but it atleast moves. If i have it pushed in doesnt move at all
