Running Rich - classic white smoke and heavy gas smell - 02-23-2011

My dad asked about my new muffler (FRPP 'touring' muffler, so I started the car to let him hear it; and he pointed out that I'm running rich. When I walked to the back of the car, sure enough I could smell the gas and the white exhaust never cleared up.
Is there an easy way to fix this? completely stock (to my knowledge) 05 4.0 auto - should I just bite the bullet and buy my tuner and CAI now?

Well...what's the temp where you are now? Was your car already warm when you showed him?

I'm not sure you are actually running rich....usually the factory tune is made to where you will run ever so slightly lean from my understanding.

I'd go ahead with the CAI and tune regardless.... seeing as I just got mine done lol IT'S AWESOME!

White smoke ususally indicates condensation/moisture/coolant. Black smoke is a running rich situation. Is there a check engine light?

Regardless, it sounds like a perfect excuse to buy a CAI and tuner!


To everyone out there, wherever you are. Remember, the light at the end of the tunnel may be

chasing you down in their own Mustang!

If it is smoke and white it is burning oil.

Condensation/moisture/coolant would be white but steam not smoke.

Rich would definitely be black as you stated.

Are you sure it is gas smell? Coolant that has run through the combustion chamber smells pretty strange.

A cold engine runs rich until the cats and 02 sensors start working. If the white stuff fog/smoke goes away after 1 minute of driving and your coolant level and temperature, and oil level is normal, you've got nothing to worry about.

It was about 50 outside (that's a complete guess), but I had just started it up; so it was probably just the usual warm up exhaust. I'll have to stop and get gas shortly after leaving home tomorrow, so I'll check it then. That should be enough to dissipate if it's just the normal warm up thing. I'll let ya know what I find out.

I WOULD just get the CAI and tune ANYWAY but I'm beyond broke with a roush bumper in the garage that needs paint among other 'life' things.

blue is oil. It looks light but it has a blue tint to it. Coolant also usually comes with a sweet smell.

Sounds like a cold start. Mine is rich enough on a cold start that if I back through where the exhaust was I can smell fuel even with the windows up.

I've always heard that, but I disagree. I believe Gaylon is right... Coming from a guy who's turbo leaks oil past the seals on occasion and had to have it rebuilt twice already. haha.. I KNOW I was burning oil and it was a HUGE white/gray cloud behind me. Perhaps the grayish could be called blue by some, but it was more white than blue.

it's a journal bearing turbo.. Just straight oil, no water/coolant
