HELP!!!Need your Expert Observation

[TJ-SRT10]

Guys,

I started this new thread to get widest viewing/reviewing:

I recently ran the thread: Pulling the #9 Plug...I did complete
that the plug pull and replacement with OEM Champion Platium.
First off, the truck runs great now and appears to have gain some
mpg's as not burning as much fuel as before. I've attached a pic of
the old plugs and need your diagnosis on them. Please, all comments
are welcomed as I want to ensure that there is nothing seriously going
wrong inside the block. I you all have alot of knowledge about the trucks
and the enter working of the engine...(Prof, FastJack, Black1, RedSRT007)
and the rest of the members here. Oh, yea its an RC 04 46k. I do drive my
daily. So chime in. Thanks.

Oh Yea, also within the last month I did run some octane boost in it for
about 2 tanks about 2 weeks before I did the plug change.

does not look bad just looks like one side is running richer then the other maybe a O2 sensor just reading wrong.

nothing to really worry about. the O2 are really cheep and might help.

not bad at all.:rock:

I cant see anything wrong either except like you said they have 46k on them. Everything wears out it was just time.

Can someone PM me the proper gap for the plugs for our trucks. If I remember correctly when I put new plugs in I ran a .035-.040 gap. What is the gap supposed to be?

 

[dragon]

the gap is .033 - .038 and your oem plug number is rc12ecc.

Its near to impossible to inspect plugs online unless your very good with a camera

When I read my plugs (I pull them out once a month to check them), I use a 10x magnifying glass to REALLY read them. Unless you have an Obvious situation it wont show up very easy from a non-detailed pic. When reading plugs, depending on what you want to read, you need to pull the plugs right after a WOT run or else you will just wash the reading off the plugs. I break my plug-reading into 3 groups....Fuel, Timing, and heat range.

From that pic everything looks normal, besides the standard air distribution issues the gen 3 manifold has. If you want me to check them out, feel free to send them to me, and Ill check them out for ya if you want ...


Take care!

BBQC, inside the engine bay next to the airbox the matrix state .035 gap.

Say it ain't so!

Didn't think those two were possible at the same time on these trucks. Anything significant or just smoother and a .01 mpg or so? :dontknow:

For having 46K the plugs look very good, some slight wear on the center electrode which is normal.

I would gap them on the low side .033 and use a wire feeler gauge to do it..

Using antisieze on the threads is also a must. Do not get any antisieze on the electrodes, you can create a misfire condition if you do.

Thanks Guys for all your responses. FSTJACK, if I change the gap to .033 is
the wire feeler gauge some sort of electronic reader that give you dead
accuracy for gapping spects:dontknow: I am not familiar with that device.
I am not ashame to say that I not mechanicially incline when it comes to
internal combustion engine and wiring specification. That is why I
put the questions to those that know best.:rock:

Tony a wire feeler gauge has wire instead of flat gauge material to measure thickness with.

If you do not have a wire feeler gauge just use a regular feeler gauge. It will work OK.
Pic of one type of wire spark plug feeler gauge. The ends with the slots are for adjusting/bending the ground electrode clearance/gap.
