i have a 2004 civic ex coupe sohc no vtec and i cant seem to do over 80 i know how to drive but i cant seem to get my car faster than 80 also at 60 in 5th it revs at about 3500rpm can anyone help me if theres a problem? im pretty sure it was a company car when it was first bought so there may be a speed limiter on it but i doubt it.

might just need a good tuneup. new plugs (ngk or denso), clean out intake parts, check fuel pressure, new air filter, auto-rx.com oil treatment system if the engine was neglected (probably), make sure brakes arent dragging, tires at around 35psi, etc. here is a good start.

get codes read in autozone? some of them do not trigger engine check.

Ive hit the limit at 115mph in my stock DX, just do some basic tune ups and you should be good to go
