Resistor / Non=Resistor, Spark Plugs Options

[Randal]

Embarrassing story, but worth telling.

My motor is fuel injected and the engine management system is Link.

I called NGK to ask their technical support guys why they didn't include the caps on the plugs. The plugs I've been running came without caps as their primarily purpose is as a motor cycle plug I learned.

The guy asked me about my engine configuration and then asked me why I wasn't running resistor plugs. He explained that non-resistor plugs could interfere with the signal going to injectors or other critical electrical functions.

He also said I should try the new iridium plugs ($$) in the same heat range as they last a long time.

Anyway went ahead and got the resistor plugs, (CAREFULLY) gaped them and put them in.

When I started the car up you could immediately tell the difference. In the past it never revved this smooth. (IMG:style_emoticons/default/flag.gif)

It'll be fun to see if this plug change makes a difference at an event.

just wrap all the FI wiring in Reynolds wrap (IMG:style_emoticons/default/happy11.gif)

my friend has a Volvo that he built the crap out of (makes more HP/TQ than my engine!) and he was having issues with his megasquirt. So, questioning if there was too much "noise" under the hood, he wrapped all underhood wiring for it in aluminum foil and it fired right up and ran perfectly. Of course, he worked on swapping the plugs and the wires and so forth, but hell, if it were my car, I would have stuck with the 20 cent fix (IMG:style_emoticons/default/shades.gif)
