So the sentra. I picked it up for a daily driver from a family member. It was running like crap. First off, I scanned the obd2 with uprev that I have for my Titan. There was a misfire. I narrowed it down to a bad coil pack. I replaced the bad coil and the plugs for good measure. The car has just over 100k on it. It ran perfect for 10-15 min of normal driving then the cel came back on and it ran extremely rough. It wouldnt break 2000 rpm. I scanned it again and pulled a P1102 code. Maf. I cleaned the MAF, cleared the code and it ran perfect for another 10-15 min of driving then did the exact same thing again. Scanned it once again and pulled the same P1102 code and a P0731 code. That one said gear 1 incorrect ratio. I am just not convinced that the MAF is the issue in that if it where bad, why would it work like new by turning the car off then right back on. I am just looking for a little direction and I am really looking forward to getting 30mpg in this sentra as a daily driver over the 8-10mpg I get out of my titan.
Any help or insight from you sentra gooroos out there would be much appreciated.
Thanks in advance
