got a 2nd hand sentra 06 GS matic. the idle shoots up(2-3k) for 1-2 sec then returns to normal(1K) . the engine
appears to conk out especially after a full stop but recovers.Does anyone recommend just a tune up?BTW, there
is a digital display on the top leftmost part of the dashboard which has 3-4 blinking lines but disappears after a while. What
indicator is it for? thanks in advance!
