And also for ford USA units, i would strongly recommend na pa-check nyo sa mechanic ang health ng high tension wires. Sa US kasi they consider this a periodic replaceable part but its not the in the users manuals. In most jap cars, kahit 10 years na car mo , the high tension war is as durable as the engine. Pero with ford units especially explorers and expeds, Americans replace this part kagad, dont know why. I had this problem, i bought a third party set of high tension wires from a relative na bslikbayan. It solved a nagging 3 month problem noon. Yun intermittent stalling as well as mikd misfiring.

Im thinking it might be the stop and go traffic here in the metro. It's wearing off the wires faster.
