93 YJ engine miss
2.5L I4 FI starting out cold...and drive about 1-2 miles, then motor will jerk and almost miss fire but will not stall...will only last for about a mile, and then after that it runs fine. anybody run into this strange behavior ? Im thinking blocked port injectors or dirty fuel filter ???? any suggestions ?

Spark plugs? I would do a full tune up and see if that works.

Check your vacuum lines. On older jeeps they get brittle and break.

mine just did for the 1st time the other day during a hail storm, missing and jerking etc., scared the heck out of me, thought my daughter and I were walking home. But then it just went away and started running fine again,,I dont have a clue what it may have been, I just blamed the weather,,figured something maybe got wet or something..*LOL*
