Hi all

I have a Prado 3.4l petrol which I purchased second hand. Since purchasing the car, I have smelt a rather strong exhaust smell everytime i stop the car or sit in the one spot at idle. The best way I can describe the smell is that it smells like and engine running rich. Its not a fuel smell but more of an exhaust smell.

I took it to my local Toyota dealer who checked the car and said they could
not fault it. I believe something is wrong and the smell is often commented on by friends.

My Prado is a 2000 model with 30,000km.
Any comments much appreciated.

Assuming you haven't an exhaust leak, what about a plug missing, or out of place in floor pan?

Perhaps the rear vent is allowing gas top get back into cabin, think the flap can stay open, or get propped open by accumulated bull dust.

Bob Y,

Even when I am standing next to the car I can smell the richness of the engine.
The toyota mechanics at my local dealership obviously didnt really take much time to check it out.

My wife's V3000 1993 (had it since new-my ex Co car) also has the richness smelling exhaust. 110K on the clock.

Mybe you should check around for fuel usage figures. I must admit, the V3000 is rather thursty but does only 10K a year, mainly around our suburb. It desperately needs a good set of plugs & or leads for a few years now (been there for 2-3 years now)

When did you service it?

My previous car was a Prado V6 (1996). I felt there was also a strong petrol smell just about from the time I purchased it new. The dealer said there was nothing wrong with it. I did notice that exhaust pipe on some other V6's seemed to be less dirty than mine. It could be a driving issue. Late in its life with me, the fuel economy went from an average of 15 lt/100klm to 17. I tried many things to solve problem, however a suggestion from this site (MAL58) said to check one of the sensors in the fuel system that can get grimed up, sending poor data to computer, running fuel system rich.
Once checked, this improved the economy for a few months. Car had done 120,000 klm at this stage.
Try searching under RV6 for more details.
