    Hello all,

    I recently replaced the spark plugs and wires on my 01 PreRunner Dbl Cab. I travel 45 miles to work everyday, all interstate, and I have noticed now, after changing the plugs and wires, that I hear what sounds like "static" through my speakers when the radio is on. When you let off the gas pedal the noise is more like a popping sound, like the popping of a spark plug sparking. I have also noticed that I am now getting about 45-50 miles less between fuel stops. Any suggestions? Thanks.:confused::help:

    Did you gap the plugs? Static is usually caused by the alternator.

    I was informed NOT to gap the plugs since they were double electrode.

    Im not familiar with the double electrode, but im pretty sure it needs to be gapped. Let me do some research..

    Improperly shielded wires would be my first guess.

    I have the same problem that you described a while back where you changed the plugs on your toyota and started to notice the speakers picking up a static noise and popping especially on decelleration. Did you ever solve your problem?
    Thanks,
    Jim

    I chased that problem for quite a while. I unplugged all my wires and re-installed them, making sure they were tight on the plugs. I finally wound up retorquing the sparkplugs, (I think it was 15 ft-lbs), and then made sure that the coil pack and waste spark wires were tight and properly fitted on the plugs. Problem eliminated. I suspect the plugs weren't grounded properly in the hole and were arcing, thus creating static.

    Hope this helped.

    Why people feel the need to put overpriced German platinum garbage in their Japanese copper lovin trucks confuses me. How bout some Denso or NGKs oem spec plugs? Guess those mighta done the same thing if not tightened properly too tho.
