Hey guys I have a 2001 wrangler, 2.5, 5 speed.
I noticed a slight hesitation that has gradually gotten worse. Yesterday it started bucking really bad. I changed the plugs, rotor, cap, and wires and while it runs a little smoother the hesitation is still there.
-when it bucks/hesitates the tach will jump all over the place
-only seems to do this after the motor has warmed up
-the hesitation is intermittent, sometimes it will go almost the whole day with no problems, other days its there almost all the time
-it also seems to buck/hesitate when I hit bumps in the road.
Im at a loss, the tach makes me think it still has something to do with the ignition. I don't loose any electrical power when it is doing this; Iíve tightened the ground strap and cannot find any loose connections.
Thanks in advance for any help any ideas? ignition coil?
