Hi all Cefiro's sifu,
Just got my Cefiro A32 2.0 2 months ago. Changed the flywheel oil seal due to oil leak. However after that whenever I am constant on the gas pedal @4th gear (5% <-> 50% throttle), the RPM move down and up, repeating unless i let go the gas or press more to force it go down to 3rd gear.
Does anyone of you encounter the situation above. It is quite annoying and I'm worry continue use will either damage the valves or the gears.
P.S. I plan to use it as a highway car but now, it has become a city car (4th gear problematic). Can't imagine I have to drive this car with overdrive off... :(
Attached the consult RPM(series 1) vs Speed(series 2) graph. Sorry that I couldn't get the Scan tech nissan working (so i can read the TCM's data)
