So ive had a weird problem with my jeep lately ill be driving down and all of a sudden the hole vehicle jerks, rpms jump down low, it loses all power, then it goes right back to normal, a minute ago it happened to me and i pulled in the driveway and pulled it out of gear, i sat there a second then the roms went really low ( like 300-400 rpm ) then it went back to about 800 ( idle ) it did that about 3 times then died, i started it back up, moved it then it shut off again. Wtf is wrong?? Bad gas? Fuel pump/filter? At first i thought my clutch was going out but it still did it when it was out of gear and idling. I need to know this is my DD. Thanks in advance.
