blue is oil, white is coolant, dark black would be running entirely too rich.

First step is checking the ignition and anything to do with getting spark to the engine. If you're not getting enough spark, you're not burning the fuel.

do a tune up, u got a lot of miles, so im sure some new plugs, a new rotor and cap, and a fuel and air filter can help out a bit, also check out ur timing, u might need a timing belt and water pump

[civilizd]

water pump and timing belt can affect exhaust color?? if thats true please some one let me know!

[ledzep09]

i dont think its got anything to do with color but maybe the efficiency of your car and if its working properly that determines if your exhaust is comin out healthy or not.
