What can be wrong??
When it runs normal the oil pressure gauges it at 40 but when my car starts to run rougher its closer to the 20 mark. And at idle when its rough the needle is right above the red(danger) area on the gauge. And black smoke(not real thick) comes out the tail pipes, it doesnt last long but just when I press the gas harder than when i was cruising.
Anyone know what this means???
