I know my 4a is idling high, but im not sure how to fix it, but also ive it sounds like theres a small humming or rattle coming from the motor. i know what valve tapping is and this doesnt sound like it, anyone have any suggestions?

never mind it was all a spark plug issue, anyways does anyone know where i can find a set of plug wires for the 4a? is there anything other then oem that i can use?

you can contact at pass-racing and ask if they have TRD ones at their website (passracing.com) or contact Herb at Cabe Toyota. It's listed under perfomance in the cabe toyota homepage. IMO, the oem ones will do just fine. Why pay more for something that you won't notice any difference.
