Question about 2000 Jeep Grand Cherokee
Motor runs fine until 80km per hrs
then , the motor start to buck until 100 km pre hrs if I go over that speed , runs fine
Can some one help me
Since #1&6 are the furthest from the center of the manifold (if it's a 4.0) I'd suspect that either the manifold gasket is leaking a bit and leaning out both cylinders, or you have an ignition wire that has worn through a bit (in this case either #1 or #6)and they are either crossing or in close proximity to each other permitting cross fire.(not extremely likely but possible) The other item I'd check is your fuel filter. A partially plugged filter will cut down on delivery, effectively lowering available fuel when you need it most (pulling in mid range) Also, make sure your air filter is clean!
