tune up question what should i go with?

[jbashaw]

so Im about to do a total tune up and Im trying to figure out what plugs/wires/cap i wanna go with... Im leaning towards the gold cap and rotor from autozone, mid grade wires and maybe Bosch platinum plugs. i seen a performance plug set online by accel for $29.. that's like $6 more than the Bosch.... first question. "would it be a waste to put performance plugs on a stock coil? and spiral wires vs suppression? i usually just go with the cheapest stuff but i wanna upgrade a little...

Is your motor mostly stock?

if you want to stay relatively stock..

stock replacement coil, motorcraft cap and rotor, Omni-Spark 8mm plug wires from O'reilly's.. american made in kentucky and i had them for a while.. good wires.

NGK V-powers for the plugs... best plug out there.. the whole thought of Motorcrafts are the best for these 302, 351's, is horsecrap. NGK's are similar if not IMO better, and they at some places cheaper..

Bosch plugs/wires aren't bad. Decent quality, don't seem to crap out before the next tuneup. As a matter of fact, I ran a set of plugs and wires for WAY too long and the plugs crapped out before the wires.

So long as its not a set of Autolites...

and the autolite thing i find hilarious...


Autolite(Honeywell) produces the Motorcraft plugs...

I always had better luck with fomoco cap and rotor. unless you are going to upgrade to an MSD ignition I wouldn't expect much gains with anything fancy. All or nothing bud. just the old 5.0 mustang guy in me

Yeah the 302/351 aren't quite as picky about spark plugs as other motors are. I agree with that.

Update

so i just installed the duralast wires and duralast cap autolite plugs.... it made it run much much better BUT.... the check engine light came on for some reason? haven't had a chance to pull the codes yet but i was wondering since it had ORIGINAL I repeat ORIGINAL wires on it dated 1995.... could the New wires and cap make it show lean or rich? since it is actually firing right? OR maybe i loosened a vacuum line? haven't had time to check the codes or lines.... any ideas?

 

[jbashaw]

yeah its all stock Im not looking for performance gains persay just want it running at its best... the wires and cap i took off were completely shot.... it just sucks doing a tune up and getting a check engine light...

pull codes.. dont assume anything...

how to pull codes with a paperclip..

buddy of mines video...

 

[emtzach]

Is the truck running normal?!?!?! if not then time to back track...

 

[jbashaw]

yeah it runs way better than before the change... its throwing codes 111 and 332... light only comes on after driving it a mile or two... Im kinda stumped on this tho I've never known a tune up to cause a check engine light

 

[O'Rattlecan]

332 is a code about the EGR valve not opening. This is unrelated to your spark plug swap, I think. 111 doesn't really mean anything, don't worry about it.

111 is a blanket code saying systems are good..

the EGR valve code is i bet you broke a vacuum line down by the passenger side manifolds while changing the plugs..

 

[jbashaw]

yeah Chris you was right.... after pulling all the plastic covering off the vacuum lines the green one going to the egr line was broke.. good thing i picked up about 8ft of vacuum line last time that happened..

i did the same thing several years ago on my old Flareside with the 351W..
