moved you to SENTRA.
how slow is
slow 5mph, 25, 50mph 100?(lol)
one of he
most made cars on earth is this , modern.
running on the road, ! still. vast . and well known and easy to fix.
Ok, there are 2 macro causes here.
- engine weak.
- or transmission slips or will not up-shift 1,2,3,4 gears
#1 has vast causes micro view, bad fuel, bad spark or weak fuel pressure and caused weak injections and low engine power
if the transmission bad, the RPM of he engine goes real high but MPH not so high. (per you yes)
check fuse first
then get the car serviced, if still bad.
RPM high means (no tachometer in dash) means hear the engine spin up fast even screams.
the clear proof of transmission failure. (shifter in D )
