Transmissions not shifting out of second gear.
do you mean warmed up ,at idle, the rpm surges up and down with out foot on gas ?
When u want to go to downshift bring Ur rpm down to 1100 but in out of gear and rev the engine rpm to 1400 or 1500 don't over rev it.
2002 nisian max engine rpm 2000 but will not go above has no code
We drove the automobile down the street to go to a block party.
Clogged Cat converter
bad connection
That it is probably stuck in low range
The rpm required for an alternator will depend on the result that you want. At the very least, you will want 1200 rpm. The rpm's can go as high as 5000.
some say go onger is better than rpm but some say rpm is better because it was more serious and go onger was like a kidde show
If it's all stock, you probably shouldn't go much over 6500.
The spark control is also a REV limiter, you could replace it and chance blowing up if you like. It still wont go over 50
You have water in the mass air.
