8 Spark Plugs

[Birk]

The engine in my 2000 Ranger misfires, but not all the time. Also the enginelight is on, but Ford couldn't find any codes when they tried to read it.
But one of the sparkplug cables was damaged and someone had tapet it with electrical tape.
So I'm going to replace all the plug cables now, should I change the sparkplugs as well?
What kind of sparkplugs should I get?

1994, 8 plugs, suck

i changed mine a few years back.....time to do it again though. i don't recall pulling the intake, used extensions and a wobble. seems to me i just stuck my hand back there to get them finger tight, then snuck in the wrench and finished. I'm not a real mechanic, just smart enough to be dangerous, took me 4+ hours to finish.

On my 2000 2.5 I find it easier to remove the upper intake manifold.
Once the upper intake is removed you then have access to those two coolant hoses that run to the intake and then down into the block. Make plans to replace those with 1/4 ID heater hose. Also Ford recommends replacing the PCV every 60,000 so throw one of those in as well.
My first set of plugs were ford, from the factory and I got about 100,000 before replacing. THose plugs were double Platnums. Ford apparently no longer makes double P's for that truck and recommended a single Platnum plug. I install those and replaced them at 60,000 and they looked like crap. This time around I used double platnum Autolites so hopefully they will last to 100,000.
You need a new gasket for the EGR and the upper intake when all done.

Where did you find the individual gaskets?

Thnx

the upper intake gasket is actually called "Plenum Gasket"
