new problem after intake swap...

[xsoutherngun89x]

i have a pretty serious issue here guys, :nonono:. after my PI intake swap i keep getting a cylinder #4 misfire code
and fouling out plugs. its went through 2 plugs and im confused. it ran fine for a week then started this... :help2: :slap: :help2:

 

[xsoutherngun89x]

any ideas yall?? im stumped... :dunno:. im really at wits end :rant: :rant: :rant: :rant: :rant:

 

[killagt]

are you sure you torque those bolt down really good ?

 

[xsoutherngun89x]

yep, 22 ftlbs. in sequence also, lol. I think i found the problem though. I havent changed
the wires out yet due to the fact they were 9mm ford racing ones :hammer:, and its most likely
gonna be the wire giving me my problems. It ran fine this mornin with no stumbling or missing
so i know its not gonna be the plug. I need to change the wires anyway so ill see if that
works. lol.

When I did mine I got a misfire..but it was due to coolant being down in the spark plug hole. I would think that if you changed the plug already most of the fluid would be out of there..but it's food for thought.

check the plug wires first....

if they are ok, then Im thinking it could be that rear coolant passage by number 4, that could have possibly started to leak??

 

[xsoutherngun89x]

yea im gonna put new wires on as soon as i can this week, lol.
as for the coolant in the plug hole, i made sure to throw some
compressed air at it before i put the wires on after the swap. lol.
im almost certain its going to be the wire, least i hope so. i would
much rather save up for my upcoming mods rather than piss it all
away chasin a problem, :rant:. but hey, i knew what i was getting
into when i bought a mustang, haha. couldnt help it though, i just
could never see me driving a GM car... :slap:. lol.

ok, UPDATE!!!


problem seems to come and go. mainly runs great till it warms up, then i get the stumbling and fightin from a misfire.
pulled the wire off and plugged a spare plug into it, started the car and the spark IS hitting. im now confused... :help2:. lol
im hoping that it isnt coolant seeping into th ecylinder cause i do NOT wanna have to take that damn thing back apart
just to change the gasket. i have a little leak on the back water passage cause my dad didnt wanna wait for the RTV to dry
grrrr....(dad argued me down and i finally shut up to keep peace). Its not bad, just annoying and i can deal with it, i cant
deal with this miss tho. Anyone have any suggestions or has anyone had a similar problem after the swap???

p.s. should the problem be with the #1 or #8 cylinder???

if you didnt wait for the RTV to setup you are screwed. It needed 24 hours or so to be strong enough to hold black the coolant flow.

 

[xsoutherngun89x]

yeah i dont have a mis anymore but im still leakin at the rear coolant where
the RTV wouldve worked, grrr. Sometimes its better to just argue and piss
someone off than let things go their way (ie...the WRONG way). Guess
i can plan my weekend to fix this if it gets worse. I know for sure its not
gonna get better on its own...haha. Im gonna hold off as long as i can but
i know im prolly gonna end up doin that this weekend. lol. :slap:

24 hours is the key
