STARTING PROBLEM, WONT IDLE,BLACK SMOKE, ONCE STARTED IT SOUNDS ROGUTH


This problem is a bit more difficult to diagnose because half of your symptoms rule out half of the solutions. I would think the ISC control could be dirty or not working or your fuel injectors are sticking open.

With black exhaust smoke you are running rich. Often the "Cold start sequence" is at fault for poor starts making the engine too lean when the sequence fails. An intake air leak can cause the engine to run Rich, causing the black smoke, rough idle, rough running conditions. This is still a possibility, but the on-board computer usually sets a Code saying you are running "Lean" and then enriches the fuel ratio and floods the engine by itself.

Now the fuel injectors can cause several of your problems. For start-up problems, the remaining fuel pressure can dump fuel into the engine as the car sits because the injectors are sticking open. Someone would need to perform a fuel pressure bleed-down test to see if you have this problem.

Another way to verify this problem is to capture the oil during an oil change and smell it for gasoline fumes. The dilution of the oil will destroy the engine. If the injectors are found to be the problem, a new oil filter and change are needed.

1990 Jeep Wrangler 2.5l idles rough/ black smoke/ fuel odor


You could pay a garage to diagnose the problem cheaper than throwing more parts at it.
The problems may be connected or they may be different issues.
Yes I would change the oil and filter, but first I would make sure the fuel system is not dumping too much fuel into the cylinders.
The O2 sensor helps the computer decide on how much fuel the engine needs, along with the other sensors. And you said you have already replaced the O2 sensor.
A mechanic would take a scanner and "read" the sensors and look for something out of normal range.
The fuel pump and fuel filter are off the list as far as causing a rich mixture goes.
I would start with the rich mixture and then see if fixing that issue takes care of the no start when hot issue.
Change the oil and filter first, and see if the injector is on too much.
You can watch the spray and tell - at idle it should be very light.
Also look at the engine temp - is it warming up to normal 195 degrees? Can you tell if the fuel pressure regulator is blown and pouring fuel into the throttle body ?
Without a scanner its going to be more difficult, but not impossible to diagnose.
Let me know what you find out.

My 2001 kia sephia starts but is missing badly


Sounds like a bad coil pack 1 and 3,if you change it and it's no help,see if you can find the vacuum hose that goes to the fuel pressure regulator, ,if there if fuel in the hose ,it's bad

95 Jetta won't start consistently


Probably a good idea to change filter. Gas in oil due to attempted starts and flooding. Additives will draw out water and make white smoke. Been there, seen it. New gasahol will separate within 6 months and will draw and accumulate moisture like diesel. Since no default lights are on you could still try autoparts store like Autozone or similar and ask for test but without faults probably a no show. The additives could cause high idle until you are burning 100% gas. Check to see if all vacuum lines are correct after removing air filter.

Idle too high +goes higher when put in gear (manual transmision


IAC valve problem. Nissan has a updated harness (with one way diode inside of the harness) to prevent backfeeding for the IAC valve and a new IAC valve also gets installed. That's where I would look. IAC valve or "idle air control" valve.
