2019 ford mustang gt maf sensor replacement

[Cjxtreme09]

Ok hopefully this is last time. Update i changed new maf sensor. Reset ecm pcm. Let it sit for 10-15 minutes plugged everything back up started car ran weird for like a minute then It sounded normal. But in the process it began to smoke immediately. Black smoke from tailpipe. But after a few minutes it went away. Drove it everything seemed ok. But then it started smoking again I checked the oil and it seemed like all of sudden I had like a large amount of oil!!!! Out of nowhere. Like wtf what am I doing wrong here?? Is the maf sensor defective?

Didn't have this issue before maf replacement

Sounds like your car is burning an unusual amount for fuel. Could also be due to oil contamination. Have you checked the injectors? Also, how's your air filter? All good? Looks like your car is running rich. hth.

Air filter is ok. Looks fine. Haven't checked injectors yet. Thought about doing an oil change to see if it solves the problem. Haven't had a oil change yet. I know I needed one. Just Haven't gotten around to it. It's just weird all of th3 sudden that happens

Sure sounds like it. If it is it must be massive to raise the oil level.
Op, you absolutely need to change the oil, probably be best to do it before you drive the car again. Really good way to destroy bearings running oil that is that contaminated. I'll bet that when you drain it the oil will reek of gasoline.

Got you i drove to work today. Have to drive 15 miles home hope it will be ok

I hope so

So the fuel leakdown. What do I need to do for that? And if I change the oil will solve the problem?

 

[ORRadtech]

Changing the oil has nothing to do with fuel leaking into the oil. All it does is get good oil into the engine to protect the moving parts.
If you don't diagnosis why fuel is getting into the oil and fix it the problem will just repeat.
The most likely cause, I'd think, is a stuck open injector

Shit you know what. I know where I may have messed up. Car takes 89. Told from previous owner. The first I got i put 87 gas in it. And my wife drove it twice and put 87 in it. I bet that could have caused my issue. It was felt like it would stall. As if it would run out of gas

Sorry mate that's not the problem. Your car is absolutely ok running 87. the timing just won't advance as far as on say 89 or 93 ect.

Edit: Just saw you made a new thread about the fuel.

Why was the MAF sensor changed? Were you having issues previously?

The last owner referenced a specific octane. Is this car tuned? Modded?

 

[Cjxtreme09]

It is tuned. Not cats. That's it. And the maf sensor wasn't working properly. I was told if I unplugg it while car is running, and it stays on then it's bad. I was having alot of surging and close to stalling situations. So I replaced it and that's when I had my problems. Smoking and excessive oil build up. Black smoke from exhaust
