I have a 1992 f150 302 five speed 4x4 and forgot what type of ignition system these truck use? can somebody refresh my memory please.

 

It's Fords TFI ignition setup.

 

It has an EEC-IV.
You also have the Push-Start Ignition system.

Thanks for replies guys, quick question, do all spark plug manufactures use they same standard to determine heat ranges?

I ask because I'm trying to experiment with creating a hotter spark using 0 ohm wires and non resistor plugs.
I bought some Accel 276S plugs (non resistor) with a heat range of 6 but had to return it back to the NGK UR45 (resistor) with heat range 4 because it was acting like it had a misfire.
After keeping the 0ohm wires and NGK UR45(resistor) plugs it runs fine, so the only thing I can think of is the heat range is different.

 

Are the standard plugs fouling and with what: oil, fuel?

 

No fouling, just doing a upgrade to the current ignition system.

 

No, all spark plug manufacturers indicate their heat ranges differently. I don't recall which is which. But generally speaking, you shouldn't need to be messing with heat ranges, unless you're getting oil or fuel fouling. A "Hotter" spark plug has *zilch* to do with the spark the plug produces. It's basically an indication of the heat range at which the spark plug will remain "self-cleaning" and not load up.

 

I was thinking the heat range was effecting the performance of the new non resistor plugs I tried running, but it looks like non resistor plugs in these trucks are a no no, either that, the anti seize I used on the threads was causing the misfire.
