Nissan Repair Questions? Ask a Mechanic for Answers ASAP
Hello my name is ***** ***** thank you for question.
Yes, you just ask your question. Also let me know the year and model Nissan.
Let me know.
Do you have the exact code number?
?? That is Odd. They normally share the code numbers... So They scanned it for you and told you it was a coil and sold you a coil?
There is no Service Engine Soon light on now?
Do you find that it will accelerate if you apply the gas lightly? but if you give it to much gas it bogs?
That is normally due to a MAF sensor or a vacuum leak.
When it comes to the MAF ( Mass Air Flow ) sensor I strongly recommend you get the part from the dealer. I would have it checked to verify. But most of the time when the MAF sensor does not meter air properly it won't cause a Service Engine Soon light cause it still meters air, just not properly. If you were to get one from auto zone, that is considered after market and After Market ones never work right. They never meter air properly and if you do get one that meters air properly it will flat line 02 sensor operation and have you changing parts that does not need to be changed.
Just try to remember, when it comes to electrical parts like Sensors, get them from the dealer.
If you have any more questions on this, please feel free to ask.

I hope I have provided you with Excellent Service.
Ok.. But you don't know what code you have correct?
Well there is no way to guess what code you have. If it's acting like what I described, I would check the air intake duct for any leaks. If you don't see any leaks. I would recommend you have the MAF ( Mass Air Flow ) sensor checked and replaced as needed.
When it comes to electrical sensors and parts, a scanner would be required to help verify the issue so it can be resolved.
If you feel the vehicle is unsafe to drive, if you have any type of road side service. I would have them bring it to your local repair shop to verify my thoughts for you.
If your intake duct has a leak, it can make it sound louder. Where if you have unmetered air going into the engine it will act this same way.
I would just double check the air intake duct. That could be what sounds louder and will cause the power loss.
If you do have a exhaust leak, that should not cause this issue. If you have a exhaust that is loud, you would need to go through the exhaust to isolate the leak so it can be repaired.
Can you just check that Air Intake duct to make sure there is no splits in it and that it's properly secured on the air filter housing and throttle chamber?
Where did you get the MAF sensor? Auto Parts store?
