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!
Do you have a scanner to monitor the fuel trim readings? Also, do you have any Mods to the car? K&N air filters or cold air intakes or something?
Let me know..
ITBS... Intake Throttle Body Spacer?
They had duel throttle chambers on the 2005?
Is the car all stock?
What Mods does the car have?
If you start the car and warm it up, at idle, what is the short term fuel trim readings (STFT ) or Alpha?
oh wow.. Ok, this is a completely mod'd car...
Is this setup for racing? Ecm Reflashed? Is the fuel tank Sumped?
did you put in bigger injectors also?
It sounds like this is heavily mod'd. A sump tank put a low spot at the back part of the tank so when on heavy acceleration, the fuel will all go to the back of the tank to the fuel pump so it can pump fuel properly. If you leave the factory setup, depending on level of gas, if you accelerate hard it pulls all the fuel away from the pump
How much gas is in the car right now? Also did this start out of the blue?
are you using factor MAF sensors? Do you have MAF sensor cleaner?
Ok.. So no MAF sensors so the software is totally not factory also...
How much gas do you have in the car?
What grade fuel? Super / Premium? Do you have this car setup for pump gas?
This one has me thinking. The car is more or less far from stock. This may require a tune to the Ecm to re-balance the fuel trim
