tune up

just replaced the cap, rotor, wires and plugs. the plugs that were in there were the original plugs(100k miles). the old wires had a resistance of over 6 ohms. runs much better now.

I am assuming you pieced everything out. I've heard of 'tune up kits' online. Do you think they are any good?

The old wires had a resistance of over 6 Ohms? The ignition wires should have had something over 20K Ohms of resistance which is purposely added to them to prevent them from generating electrical noise/static that can screw with the ECM and the radio. It's FAR cheaper to make ignition wiring with essentially 0 Ohms than to make it with the amount of resistance needed to prevent them from generating noise.

Due to the extremely low (micro-amperes) amount of current passing through the ignition wiring, the added resistance does not reduce the voltage provided to the spark plugs in an amount that is meaningful. Ohm's Law and all that.

So-called "Low Resistance" ignition wire sets play on people's misunderstanding that low resistance must be a good thing but it's not where ignition wiring is concerned. For ignition wiring, the low-resistance thing is strictly a misleading marketing ploy that sounds good to most non-electronic types. The voltage reaching the plugs via standard high-resistance ignition wiring is really not much different than is produced by low-resistance wiring. The difference, due to Ohm's Law again, is totally insignificant.

quadratec does have a tune up kit, it comes with cap, rotor, wires, air filter, fuel filter, and plugs. all are just oem replacements, the plugs are champion plugs, the cap and rotor are from crown automotive, not sure what brand wires and filters are.

i went with the oem cap, rotor, and wires, got the diamond fire e3 plugs, didn't need the air filter, i have a cai.

i got everything and a set of bestop front seat covers for about $200 delivered.

all i know is that the resistance of the new wire was much lower, didn't know if it made much of a difference or not, all i know is the engine sounds better and runs better. the plugs, wires, cap and rotor were all original, never changed. all i need to do now is the o2 sensor(never been replaced)
