4g93 n.a, black smoke

[13b]

had just transplant a 4g93 abt a month ago. the problem is, can't seems to find a solution for the black smoke. sent to some w/shop n most said tht some sensors r spoilt n most probably af sensor, but i don't want to change the wrong parts as they can't guarantee it's the right part. anybody experience this b4? the plug also full of carbon(dry, symptom of rich fuel?) no matter how often u clean em. n one foreman even said maybe a wrongly marked timing belt (while changing). tired of this "maybe". any sifu can hep me out? loc in jb. thanks

13b,

R-tune does a hell a lot of 4g9x's back in the day. go look for them , they're also the guys with the sr20 quad throttle engine.

tbh there's no such thing as guarantee unless a part that can be seen with a naked eye , we will nvr know a sensor has KO-ed until u taken it out , i mean some things are meant to be dismantled 1st then only u will know ...

my 2 cents

Black smoke during rev or even iddling...?

 

[UnicornSpeed]

what injector ? 240 ? got two thing on my mind your air flow sensor and o2 sensor....pls run a scanner we be much help.

 

[artworkz]

o2 sensor no so much effect for rich burn. o2 sensor play small role oni. if car can rev well, there is no timing belt run teeth. ur car is dohc or sohc? u full set 93 convert or mod to dohc or mod block? tell me more.

 

[13b]

mine is a dohc a/t convert to m/t (eterna body). using 6123 ecu, standard injector (dunno what's the size), evo's fuel pump ( the problem start b4 tht), 454 af sensor(if i remember correctly), n it revs well, very well, the black smoke occurs while idle ( just a bit) n also while revving ( like burning house hahahha)

 

[speed2horizon]

O2 sensor is only used when idle or cruising. When ICU A/F feed back is running on close loop... Else, running on open loop.

Have u tried unplug the battery and plug back after 5-10 mins... reset the ECU.

ok, problem solved, change to gti injectors n walla.. problem solved. thanks all
