Can anybody give me any possible solution to y i'm running rich, heres the mods i have done, stage 2 extreme 16g ported turbo, ported manifold, extreme fuel pump, extreme intake, UICP with 1st gen BOV, Clutch Masters hdsb clutch, 3" thermal R&D Exaust system, HKS EVC IV Electronic boost controller, HKS Type 1 turbo timer, and B&M Short shifter kit. And another problem i have is when i start my car up in the morning i have to hold the ignition in the spot so it actually catches b/c of i don't it will shut off. I don't think its my starter, but any help would be awesome.

Why do you think the car is running rich?

B/c my friends tell me when i'm driving in front of them that they can tell when a huge cloud of smoke comes from my exaust.

What color smoke? Black, blue, white, pink? How much boost are you running on that 16G with the tiny stock 2G intercooler?

john 08-24-2004 10:14 AM

Blue = oil
while = coolant
black = rich or lean
pink = huge turbo swallowed something

nightstalker 08-24-2004 11:13 AM

Its black

nightstalker 08-24-2004 11:14 AM

and i'm pushing 14.5 psi

Could be either.

Lean : burning the carbon off your pistons
Rich : unburnt gas making its way out the exhaust

So got any help with a fix or just trake it to mitsubishi and get it tunned up?

Get an EGT gauge and a datalogger. Examine the data and you will be able to tell if its rich or not. Will most likely end up costing you the same price as a trip to Satan.

You can borrow a dattalogger or buy one, get a EGT gauge or a wideband, of drop the boost and see if it changes. If you drop the boost and it goes away, it was running lean. You could also check your spark plugs.

oh ok thanks guys

I'll be in Harrisburg, PA in a week.

I've got a Universal WB Sensor/Datalogging Software to check it out.

Maybe an AFC should be your next mod.

Note: Most 2Gs I've seen without cats smoke(rich/safe) under hard boost.

EGT is worthless. Its a FWD take it do a dyno with a wideband o2, or buy a wideband and put it in your car.
