Hi guys,
i have a my97wrx import from singapore, met a subaru mechanic today who was having a look at the tail pipe and said the car is running too rich because the inside of the exhaust is black, and not greyish black. is this true? am i in trouble.....

Hi my 94WRX import exsaust is black just inside maybe mine is too rich?

 

Get the Emissions checked - if high @ idle and has poor fuel consumption it is likely that the Lambda Sensor is fooked

Cheers

 

the inside of my backbox is jet black

 

Mine seems to have poor fuel consumtion but not high at idle it just puffs a bit!!

 

Guys Guys!!
i was told this by a subaru machanic in a third world country thats why i asked you on scoobynet to confirm, it may be a false scare. I have normal idling, and have reasonable fuel consumption. So a flase alarm perhaps?

 

I'd be more concerned if it was running lean. As long as fuel consumption is OK I wouldn't worry too much. Only way to be sure is check the AFR

 

Grey tailpipes went out with 4 star. You wll not get one with unleaded. If your car is running rich you will get black smoke on boost

 

As above

Note that scoobs do run rich anyway, but not too rich.

best to be too rich than too lean

if you start having issues with Check engine lights, then be concerned...

but a little rich is quite normal
