Spark plugs with resistors and without - What's the diff?

[webmiester]

Speedometer/Odometer ba talaga or TACHOMETER??

I had erratic idling before to the point na namamatayan ako ng makina. The plugs were new, but Migs of Speedyfix said na baka plugs ang problema. So he pulled out a used set of plugs, and voila! Nawala ang nginig, and ok na idling.

Parang imposibleng may kinalaman ang sparkplugs sa malfunctioning speedometer/odometer.

Oo n eh. Ako rin hindi naniwala, pero I gave it a try because its a lot cheaper than purchasing a new speed sensor. Sayang nga, Had I tried it earlier, I might have saved a lot since my new panel cost me some money, baka pala ok pa yung luma ko!

Sa mga websites na nabasa ko, apparently, they invented the sparkplugs with resistors at around World War 2, when certain radio-controlled triggers for TNT and bombs would go off by themselves when the triggers were near
jeeps. They later pinpointed this to the RF produced by the sparkplugs and so resistorized spark plugs were made.

The same RF might be interfering with the car's computer box, especially since these new electronic boxes are very sensitive.
