I'm new to these cars with smaller engines. I have a 2004 Acura EL 1.7 with a manual transmission. At 110kph its reving at almost 3500 rpms. Is this normal for this car. Even at 100kpm its well over 3000.

my old '91 Prelude 2.1L would run approx. 4000RPM at 120KPH. not exactly highway friendly cars.

I would do a shift count and make sure that transmission is in fact shifting 3 times and getting you into 4th gear.

ok the El shares the civic transmission and is a E.C.C.V. transmission.

if you rpm.s are high get that thing check ASAP. Take it to a dealer you trust and have them do a code pull.

if something is amiss leaving it alone WILL cost you more in the long run.
