Smelly exhaust... - Toyota Nation Forum : Toyota Car and Truck Forums

BlackCamSe · 01-18-2009, 07:31 AM

The last few days its been very cold in Jersey. Our high yesterday was i believe 12F. When i start the car in the morning the exhaust smells like a 1950's Chevy! It only smells for the 1st maybe 5 minutes of the car idling. I'm assuming its because after that, the cats are warmed up and doing their job. Does anyone els with a V6, or even I4 experience this? I know with our old 05 with PZEV it didn't smell at all.

Did you check your grandfather's '05 daily?

I start mine and drive it. Maybe ask the person behind me in the mornings?

i did actually, i always used to start it for him in the mornings. I let my car warm up for 3-5 mins in extreme cold so i have time to notice that the exhaust smells.

my 2003 will have a slight exhuast smell when i first start it up after itt has sat all night, but within 2 mins or so its gone
i havent noticed it lately, since i performed the ECM recalibration for sulfer smell from the exhaust last week.

It's because Toyotas run lean until optimal temperatures are achieved in the engine compartment. It's just to heat it up faster. You may also notice there is less horsepower too.

**PRINCESS PEACH** · 01-18-2009, 12:37 PM

in my experience, running lean is definitely not good for the engine.

BlackCamSe · 01-18-2009, 12:50 PM

i thaught the engine ran richer when its cold?

How do you guy's notice this stuff. I'm usually cold when i start the car up so im either in a hurry to start it up and run back into the warm house, or sit in the car and wait for the seat warmers to warm up and the heat to start blowing hot air at me.

I dunno ...but I push the remote start button and it's all cozy when I get in.

MrObvious · 01-18-2009, 08:05 PM

Whoops never post in the morning after only 6 hours of rest. lol

Yeah I ment rich.

My Camry's exhaust also smells bad in a cold morning but I've only noticed this in the winter really...

I'm pretty sure it's normal. You should smell the "cold start" exhaust coming out of our 08 Benz ML320 CDI. That is a strong scent, believe me and the diesel is idling so roughly that it's downright loud.
