Today i have to go out of town my car has been running great until i got on the highway . I started out going job until i tried passing a truck and picked in my turbo and then all the sudden it started slowing down, spitting and blowing out black smoke.My engine light came on but went off and it started running good again until i got back on the highway. again a tried passing a car and the same thing started losing power black smoke engine light came on and now wont go off. it only has 104,000 miles on it.
Sounds like a bad turbo to me. When you "kick it in", the engine falters and you get black smoke for a while. What is probably happening is that the turbo is leaking oil into the intake air stream, putting it into the cylinders with the fuel/air mix and causing one of two issues. Either the oil is inhibiting the combustion process, causing the falter and the resulting poor ignition, plus the oil, is giving black smoke, OR, the oil in the cylinders is fouling the plug momentarily, resulting in the fuel/oil being passed into the exhaust stream, burned in the catalytic converter and exits as black smoke. If it runs OK except when under turbo load, have that thing checked out ASAP. And, as far as the light staying on, most faults will set permanently after they occur three or more times within a certain period of time. This is ti ensure that intermittent faults won't cause false setting of the light.
Testimonial: "Yes it runs great when i don't kick in the turbo. I took it into autozone yesterday and they put it on the machine and said that it was misfiring on 3&4 i bought new plugs and wires hoping that helps."
