Hi,My name is Tim,
I will do my best to assist you
the engine is a 3,2...right?
didnt have the 3.5 in 02
are you there?
like I said, new intake, have vacuum for top of engine, new plugs, was perfect for 2 days then ck engine light came back on and the slight miss started, then 2 days later ck engine like went off and ran great for 2 miles, then ck engine light came back on, scaned it and # XXXXX misfire and multiple misfires
from the code you get
and from the way you explain the problem
it sounds as if you may have bad plug boots
this is what gos over the plugs from the coils
crossed the coils over to make sure it wasn't 4 and it ran great so I don't think the coil packs are bad
not the coilpacks
the problem is the boots
you can buy the boots at auto zone
these may cost around $50+/-
i think replacing the boots will fix your problem
we put a new coil boot on #4
new boot and replaced the coil on 4 also?
your next step is to check the compression on the #4
to make sure the cylender is sound and no blown head gasket or such
compression is good
if the compression is good
replace the 4 injector
there is nothing else left
well, have not done that
thats the only thing left from what you are telling me
we did put inj cleaner in it also
injector cleaner doesnt do anything
nothing cleans better than gas
why would it show multi misfires
i think you need to replace all boots
though you may need more on the 4
why would it run so good for 2 days then screw up
after the tune up?
because you moved the boots around while replacing the plugs
replace all boots before you do anything
those boots are bad
