Opinion Needed: black smoke out of tail pipes everytime i start it
#11
Welcome to MCF!
]How much do you know about cars? I only ask so that any of us who can help, can explain our thoughts in a way you will understand.
Is If the smoke is blue then you have a fuel delivery problem, bad or stuck open injector. If the smoke is black then it could be a one of several things. Since you do have the CEL, Check Engine Light, the first thing you should do is get that read. It could lead you right time the cause of the problem!

I'd suggest you take it to a trusted garage and have it looked at. They'll be able to read the check engine light code and go from there.

The intake and exhaust valves move up and down in the cylinder head to allow the fuel mixture into the cylinder and the spent charge out of the cylinder. there are guides the valves move up and down in. Over time the guides can wear creating excessive clearance. The valve then rocks side to side in the guide. The stem seal is located in the head on top of the guide bosses. When the valves rock side to side it elongates the seal and oil can be drawn into the combustion chamber. When the engine sits the oil accumulates in the cylinders so when you first start the car blue smoke comes out the tailpipe.
If you have black smoke coming out the tailpipe it indicates a rich (too much fuel) condition. It's possible the fpr could be malfunctioning and allowing fuel to get to the injectors while the car is off, but it is rare for it to produce enough pressure to unseat an injector. That's why I'm leaning towards a leaky injector, but that code will really help in pinpointing the problem.

If oil or coolant, in your case oil is more likely, it could cause your engine to stutter. But That's a big If. Right now with what we know, your best bet is to get that check engine light Read and take it from there.
