my car is running really rich....to the point where i had to sandblast my spark plugs that i just bought not too long ago...its smoking black smoke really back and it smells like gas really bad....my engine is a 1st gen b16a...can someone help me out on what i should do....its been smoking ever since i did the swap...

 

bump

 

how long have you had the swap?

when i first did my swap, i was smoking like MAD for a while...
it was from oil getting into the intake and exhast mani from sitting
at a salvage yard leaned over... it took a while to burn all the
excess oil off...

are you SURE you're burning rich? (using a a/f meter?)
if so, you could probably get a adjustable fuel pressure regulator
and lean it out a bit... though i wouldn't see why a stock engine
would be running rich like that... you're using the right ECU, right?

it could also be bad piston rings or valve seals...

 

if its black smoke, its running rich. any bad seals or piston rings would only allow oil to get into the combustion chamber and therefor it would burn oil.

make sure all of your vacuum lines are connected or blocked off. i was running extremely rich when i first did my swap due to an unconnected vacuum line.

 

Are the spark plugs dry (carbon) fouled? Or wet (oil) Fouled.. If you're running rich, get a FPR and lower the fuel pressure until you notice it is running correctly / isn't fouling plugs anymore.

 

spark plugs are wet...today after work i went to crank the car up and it wouldnt crank..finally i got it to run but when i gave it gas it wasnt a steady rev...it was more of a rough, purring revs...please help..

 

If you spark plugs are glossy black, you're probably getting oil in your cylinders. I'll show you what my oil fouled plug looked like. (Valve seals were bad) and what a normal plug is supoused to look like.

 

thanks man ill check that today...
