lots of black smoke

[03spicyspeed]

well when i get in to third and give it about half throttle it starts to miss and smoke really bad. its unburnt fuel i know that but it only does it at 3000 to 4000 rpms and if i floor it it wont do it or if i let off the gas a little and fall out of boost it stops smoking and shuttering so i dont know wut it could be. i changed the plugs and there is no cel

 

[Shadow102]

does it just hicup or is it missing real bad. What mods are you running

 

[torque222]

maybe coil or plugwires?

 

[03spicyspeed]

its missing real bad. i have 3in down pipe with 3in exhuast and a injen cai running 10 psi and unflashed

 

[Shadow102]

could be fuel cut/boost cut depending on how cold it is by you right now. also could be a small boost leak. Had that happen to me the other day

 

[03spicyspeed]

i know its not a fuel cut and it about 50 degrees out side iam going to reset the ecu and c if that helps

o2 sensor?

Stock intercooler piping?

 

[03spicyspeed]

ya it has stock piping on it and its fine at no boost or full boost but nothing in between

I think it's a MAF leak, there muyst be a leak somewhere in the charge opiptes. You should try relocating your MAF, that way if there is a leak or you pop of a charge pipe no serious damage occurs just the car gets slow.

You could always glue it, a lot of people have glued it as a temporary option that last forever it seems.
