so tuesday i changed the spark plugs and wires
ever since ive had this misfire where it idles at 700 rpm then it drops to 500 rpm.Its shut off on the at a stop sign.Took it to the mechanic and he says its the injector wiring .im like it happened after i changed the spark plugs and wires.i gapped the according to the oem's specs (.038-.043)
i gapped them at .041

im confused,*** else can it be?
i think its bad spark plug wiring.

i just re checked the gap its.040
changed the spark plugs to the old ones its running better but i still have the same problem.the new plugs barely made contact with the cap,cable running to cylinder#4 broke.is there anything else it can be?

check your battery. i had the same problem with missfires at idle. i tested my shitty odyssey battery(dont ever buy one) and it was no good. cam sensor wasnt getting enough voltage/amps at low rpm (idle). replaced my battery with a new optima red top. no more problems.
