Nissan Repair Questions? Ask a Mechanic for Answers ASAP
Hi, My name is*****'m happy to help you. During our conversation, I may be presenting you with different things to try, and ask you some Questions to get a better understand of the issue so I can answer your question properly. So stick with me to the end, and I am sure we should be able to get this issue resolved for you!
The MAF sensor you installed, where did you buy it? Also do you have a Cold air intake or K&N air filter ?
Well I can say as a start, that After Market MAF sensors never work right. I have won a bet with my Boss on this. A after market Maf sensor if you even get one that meters air properly, which most don't, if you do get one that meters air properly it flat lines 02 sensor operations and can have you replacing parts you don't need.
So first thing you will need to do is replace the MAF sensor with one from the dealer. Then if you have a scanner, monitor the Air and Fuel trim readings known as STFT ( Short Term Fuel Trim ) or Alpha, and let me know what those readings are after it's replaced.
Do you have a full blown scanner that can take those readings?
Can you find out if you can monitor those readings?
No problem. I will talk to you later then. I will be back online in the evening around 6 or 7 pm EST and be online till 10 or 11 pm. Talk to you then!
