I got a '95 F150 302 4x4 and was wondering what would be better to do. Replace the plugs and wires only. Or Replace the cap, rotor, plugs, and wires? Any one have experience? Also i got acess to the high schools shop lift, will this help getting the back plugs out?

 

Replacing plugs and wires without the cap and rotor is a waste of time. Might as well hit the coil while you are at it, advance the timing and gao the plugs to 0.055

 

Why would you want to hit the coil?
I have never heard of this test, I would think you would break it.
Coils very seldom go bad, I still have the original coils on every truck I own from the 77 to the 95, all seven on them.

 

You seemed to have missed the metaphore for "Hit". I meant replace it. With a higher volt coil to match the upgraded ignition componenets and timing advance.

 

cap rotors plugs wires its all worth the time.if you cant get a plug out leave it! i bought my truck and replaced cap, rotor, plugs, wires, thermostat these always go , air filter kn, put in some fuel injector cleaner, belts, tensioner assembly, fan clutch, radiator flush...hmm, oil &fuel filter. anyways this all made a huge difference in accelration and gas mileage.... do it all.

 

i agree. you might as well do a full out tuneup instead of a partial tuneup.

 

Hello all, new (old) guy to the forum.

Have a 92 F150, 5.0, a while back had my mechanic do a bunch of work including plugs, wires, cap and rotor.

After that had a light miss at light throtle just b4 downshift.

My guy didn't know how to seperate the plug wires and I didn't know either. Wires 7 and 8 were tied together and strapped to the metal support causing the miss. A sharp guy at Advance auto told me about this and he was right. Seperated the wires and miss is gone.

Had two vacuum leaks and fixed those and runs like new. (almost)

Watch out for your wire routing.

 

Thanks for all the input, and i decided to do plugs, wires, cap and rotor. I also have bought a k&n filter, similar to the one in the K&N FIPK kit, but i decided to make the pieces myself. Should only be like $70 rather than $150. ill show, pictures when im done, before and after. I also added injector cleaner and got over 1mpg and every tank it gets better, and no real change in driving.

 

The filter is $50 but the kit is $150, what is the smart choice, and i got a full metal shop at school to use.

 

Neithe is a smart choice. Get a new paper drop in filter and insulate your stock intake. The K&N filter idea is useless and overrated.

And get a Haynes manual for proper plug wire routing.
