Hey Guys,
Now that my '93 S13 hatch is running (rejoice!), I need to get it smogged at a test-only place then insured, then registered.
However, I'm having a few problems at idle, blowing a tiny bit of grey/black smoke at startup and initially when on gas.
At Idle, the engine shakes a LOT (almost hitting my ebay spl strut bar) and kind of sputters. Idle is high too, around 900+rpm.
On the gas the shaking gets better, but on accel, puffs (like I said) just a little bit of black/dark gray smoke. I pulled an "all clear" (55) code from the ECU.
I'm missing one out-of-view resonator (I think it should be ok, it's not visible at all unless you take the clutch fan etc off) and a charcoal canister.
I plan on doing the following before I actually get it smogged:
Clean AIV (air intake valve?)
Clean MAFS with carb cleaner
Clean air filter (OE panel type)
Clean EGR valve
Find/install new charcoal canister
Change spark plugs
What else can you guys (who're smog-familiar) recommend? I plan on going to a legal, clean test-only place since I have no engine mods at all. One note -- before, when the car did run, I think I was running rich. What can I do to make it run a little leaner (at least at idle)?
FWIW I have lost the intake piping from airbox to unibody so it's an airbox but just hanging in the corner, with a KN panel filter in there. Only other "mod" is spark plug wires.
Any recommendations before I go into this test-only center? Tips or tricks? ... I also plan on getting the engine nice and hot before going in, in hopes that my cat will stay warm through the 1/2 hr to 45 min. wait that they'll probably make me sit out.
Thanks in advance for any help!
