pure gasoline smell on startup...help

[Creeps228]

Well today i took my friend home, and he told the the car was running rich, he smelled the exhaust smelled like pure gasoline, he said the O2 was gone...Is he right or can it be something else?

[Mike Gerber]

It can be many other things if the car is actually running too rich. It can be a defective ECT sensor (engine coolant temperature sensor), a thermostat stuck in the open position, defective fuel pressure regulator, leaking fuel injectors, or a bad ECU, just to name a few. You can't just guess O2 sensor. You really need to do some diagnostic work here. Start by checking for engine trouble codes. Your picture looks like a 97-99 Camry, so your car should be OBD2. That means you can take the car to Autozone and they will check for codes for free.

the only code that apears is the egr valve code...p0401 i think it is, i still havent gotten it fixed yet, could it be that?

I'm a bit shady on emmisions systems, but here is my $.02. Maybe its possible the EGR system is staying open beyond normal operation and pumping excessive dirty air back into the engine. As a result, poor combustion, and voila, you smell gas out the ass end of the car. Is the car missing at all?

I'm so tempted to make a Sex Panther (Anchorman) joke right now. Now whenever someone gets into your car and asks what the smell is, just say "Thats the smell of desire M'lady."
Sorry, just had to. Good luck with your problem.

LOL

But only during a cold startup...had the car checked before, mechanic saidi nothing was wrong with it...idk, jus soem suggestions would work or is it normal

[F1000X]

Hmmm. Sensor in the EGR system is supposed to keep it closed below 55 Celcius. If its staying open I'd assume the car would miss a little, and possible produce the smell. I assume engine feels (and smells) normal while driving, right? Again, good luck.

yes it does runs greatt after warm up

and i've cleaned the egr mod, havent changed the egr valve and changed vsv valve. stupid code comes up still

Y'know, 60% of the time, it works every time...

is the coolant temp sensor (3sfe) on the front drivers side of the mill, near the top of the cylinder head?

[Creeps228]

i have no idea, i dont own a 6 cylinder engine..and i do think my egr valve is in the open position, but Oh well, shit happens

if that happens on cold start only then its normal. on my, when cold starts it automatcially goes up to about 1800 rpms and as the engines warms up its goes down. once warmed up its go about 700-800 rpms. just my two cents.

[Creeps228]

i know that, im just saying, even though this thread is old, that everytime i start the car theres at pure gas smell fro like 10-15 secs

[Black95Cam]

lol.. didnt even notices the date..

As you are standing in front of the engine, it's on coolant port coming out of the right side of the cylinder head. It is the sensor under the green plastic connector.
