After installing my zc into my car i ran it for about 2 weeks and it seemed ok. now when i start it it will miss and carry on.. so i've been through 4 sets of plugs and there all carbon fouled.. i do have crower cams but it carries about 12-14 inches of vac at idle.. so that shouldn't be the problem.. only think i can think of is gettin a apexi s-afc i dunno any ideas ??????

 

oh yeah i forgot i swapped out the old injectors cause i thought they were leaking. fuel pressure is also ok... STUMPED

 

I am guessing its your injectors, on a zc i didn't know you could do an upgrade in injectors w/o changing the fuel ratio i.e. w/o a VAFC? Just hit a little juice, it'll clean em right up.....LMAO
