Occasionally backfiring? Anyone else have this?

[TopherSho]

OFFS ... starting new thread.  Reverting to a non-meth tune does *not* solve the power fluctuations. Same issue...

Damn Internets and reasonable people being right ...  :blowup:

need to get a good log first but the hiccups continue in when not on meth and on a non-meth tune.  I need to let a tank of gas go through 1st to make sure.

Check your plugs.... you could very well have a bad plug...

 

[ZSHO]

I think you might as well install new (COP) while checking your plugs for good measures,especially if original. Z

If you have never changed out your plugs then these are a must! Usually the local Ford parts places have these available.. they were $2.95 a piece at my local dealership... they usually have them available.

 

[TopherSho]

Thanks guys.. It is on the list now. 

New boots
New COP
New plugs... IF they look burnt or white or the electrode is damaged.  I did the plugs previously when I had the non-meth tune.  what a pain in the ass they were too.

That flat gasket slides over the post on the COP and goes to the top of it. Most likely you will not need it. Don't forget some dielectric grease and anti-seize..

X2 with SBS ^^ and only the Coil on (boot) needs to be replaced preferably with the the Motorcraft/NGK brand.- X6 Boots needed @ $3.91 ea.

Simply remove the ignition coil.
Gently remove the bottom portion of the boot by gently pulling/twisting it outwards while taking the necessary precautions in not damaging the spring inside the boot.  Z

Doesn't the replacement unit come with a spring?

 

[TopherSho]

Should i get 3 replacement plugs just in case ???  ... I'd hate to take the time to get the boots put (#$%^ing pain the ass last time) and then have to do it 2x because of bad plugs ..

but i cant see needing 6x plugs ..  would 3 plugs be a safe bet ?

 

[TopherSho]

Going with 3xNGK 6150's (same as before) and 6xMOTORCRAFT WR6135 .. crossing my fingers.  Hope this is not a actual coil issue or weak o2/wideband thingy ..

I do not want to deal with the dealership with no codes ...

 

[TopherSho]

Ok i logged it.  and i am bummed as **** .. no misfires.  it backfired at 5000+ rpm several times.

log attached.  but it doesn't give me any hints.  Anyone else see anything I am not ?

 

[StealBlueSHO]

If it was me... I would buy six... what I don’t use I can put away for when it’s time to replace them.. at $6 a plug it’s cheap insurance..

 

[ZSHO]

True indeed!  certainly don't want a half a** job done. Lol.  Z

 

[TopherSho]

Will a meth wash hurt the plugs !?  should I be replacing them every 10k?  (that's how long I have had mine ..)

one last hail mary.  I will check the CAC..  it has never been a problem before... BUT it has been run HARD and above stock boost levels so it *could* be getting more than normal oil and goo in the bottom and eating it on high rpm runs. 

I will see about 'sticking' it today or tomorrow...

to be clear normal driving is perfect and strong.  it is under high load and high rpm the issue crops up.

 

[ZSHO]

The extra stress alone from the drivetrain on a Tuned vehicle should be changed more often preferably @ 12K intervals .IMO. for added reassurance purposes.  Z
So to better answer your question "Yes"
@ the end Fresh plugs,fluids=better performance.

 

[TopherSho]

God i hated doing plugs on this car .. 6 plugs it is. 

 

[StealBlueSHO]

Oh it’s not that bad. Good luck though!

 

[TopherSho]

Where and what does the boost solenoid look like ?

From Brad ""Chris go check your vacuum hoses around the boost solenoid, specifically the one that leaves the solenoid and goes to the intake pipe  or charge pipe. It looks like you are overboosting.""

is this some thing similar ?

thankx in advance..

I assume this is what is being talked about
