Lancer engine raise alot with rpm but no good speed
I am having a bit of issue recently with My lancer, when going uphill, RPM peaks and speed only goes to 60 unless i floor it RPM goes way up which i am trying to avoid. Also when car is stopped and during take off, the speed is not that much as engine raises alot then speed picks up and i can hear engine raise sound.
What could be the issue?
Lancer- GT 2013(Non Turbo)
