there is black smoke coming out from my exhaust. Is it the same problem than blue smoke(oil). Is there anything i can do.<BR>Thanks

i heard black was something to do with gas..i might be very wrong though???

it's gas residue that's not burned up properly by your engine, I had the same problem once, I had switched cars for a day with my dad and he forgot and put regular gas in the tank, and that's what it did. try putting 92+ octane fuel in your car.<P>does it do it only when you push it real hard? or all the time, cause mine did it only near the rev limiter.

My RS does the same thing. I took it to Mazda 2x already and they cant figure it out. I get no engine codes, replaced the oxygen sensor, reset the computer, changed intakes (Mazdas suggestion just as a test), injectors cleaned. They cant figure it out.<BR>If you find out, by all means, let me know. I only get it when the car is revved.

it's only doing it when i'm pushing the car to it limit, i'll try to clean my injector and i'll put some octane in my gas. If it works i'll tell and thanks for the replies

Just a word of friendly advice..please don't get offended. Avoid driving your car to the limit..it is bad for any car, and if u constantly do this, especially on a 4 banger u will have problems...i usually keep my rpms around 3-3.5 and press the gas 1/4 of the way...goodluck

i'm not always pushing my car but when it happens i can see this smoke and the guy i'm racing with is seeing it to and that is what i hate. <P>My engine is also taking some oil can this be the black smoke.
