Nissan Repair Questions? Ask a Mechanic for Answers ASAP
Hello my name is ***** ***** thank you for your question
Are you using the MPG display to determine your Miles Per Gallon? Also do you have a Service Engine Soon light on?
What grade fuel do you use and do you do allot of stop and go driving? Highway? How many miles on the car?
Well I can say that when the dealer did the timing chain work, the corrective learning is cleared. These cars have what they call adaptive learning. It learns how you drive and it will retain a memory of that. So since the work was done, and the learning is cleared, it is in adaption mode so you may see some weird or poor Mpg while it adapts.
How long or how many miles have you put on the car since the work?
