95 mustang missfiring after a few min of driving . .

[cammed sn95]

my 95 mustang gt runs good only for about 2 miles then it starts to missfire bad, rough acceleration and really noticable power loss and is running real rich as well! im frusterated with this issue. ive been running this setup for about 4 months and it never did this til i replaced the fuel filter and cleaned my K&N filter.

things ive replaced

cap, rotor, maf, o2s are fairly new, fuel filter, wires, spark plugs are good dizzy went out and i replaced it .

mods are;

e303 cam
gt40 heads
c.a.i
76 C&L maf(cali for 24's)
94\95 cobra intake
24lbs injectors
long tubes
bbk 70mm t.b
fpr set at 38psi vacc off.
u.d pulluies

double ck your firing order. Clean the MAF (k&n style filters tend to deposit oil on the MAF). What coil are you running?

Im with CC on this one double check the MAF them K&N filters are great but after a good oil'ing tend to get things covered like the MAF or IAT on the 4.6's if your maf is covered in a film of this gunk the symptoms sound spot on...
