Allright Veeky Forums so I've purchased my first shitbox (Nissan Silvia S12 hatch) and I need this thing to pass smog. High HC's and high O2. So far I'm doing this
>Timing set to factory specs
>Pulled exhaust to replace cat (was fucked already)
>crimped plug wires to prevent misfires
What else should I do? It has EFI btw.
>inb4 Alabama best state no smog Alabama best, California? more like cuck hahahaha bad state I love Alabama
Alabama a shit.
Florida master race.
>letting people tell you what you can do to your own property to use in public places
It's like you don't have any self determination.
Bump
Replace the plugs, get a new ignition coil, repalce your O2 sensors and MAF sensor
More like Cuckifornia amirite
Seriously though make sure spark plugs are good or the engine could misfire.
Is there a way to test o2 sensors? I only have one after the exhaust manifold before the cat.
>Florida master race
don't kid yourself. it's a nice state in terms of freedom with your car but for the love of god I CANNOT find a decently curvy, long, empty road to actually have fun in, it's all just straight roads and highways. I fucking hate it
t. south florida fag
multimeter can confirm that the voltage is changing in response to throttle input but that requires a bud and actually knowing how to into multimeters
This shit is why I want to move out of this fucking state. But where else am I gonna have the same kind of freedoms with my car.
>High HC's and high O2.
unburnt fuel.
Ignition (misfires) or running way rich due to fucked up MAF / O2 sensor?
Replace spark plugs, high tension wires. That's a must.
check/replace distributor cap, ignition coil.
replace O2 sensor, check/replace MAF.
If all that doesn't help check fuel injectors, check fuel pressure
