hi everyone

my car has done this only 3 times so far. what happens is im on the highway for about 10 min (above 4k rpm) and then i get off wait at a light and when i start back up the car treats 4k rpm as the redline. this has been the circumstance for all 3 occurances. if i turn my car off then back on again it stops doing it. Any ideas?

thanks

 

if its and ep3 (aka si) your in the wrong section. check the RSX/EP3 section

if its a canadian si (aka US ex)
then its probably going into limp mode.

 

are you revving it when its not moving? if so there's a secondary rev limiter that engages when the car is not in motion

Not on a k20a3.

Do you have a CEL?

 

why and the hell does your car rev at 4k while cruising?

 

limp mode?
is your check engine light on?

I was thinking check engine light too.
May be a sensor that goes screwy.

 

It blows my mind how often people post a problem and never bother checking back.

 

lol, i think they may have trouble finding their own posts. lol. back when i was forum ignorant, i couldn't find my own posts either ! lol

 

yeah it be a lot easier to answer/help with the issue if we had some more information.

 

Had this problem about a week ago.

your car is going into limp mode. Have you changed your oil lately? check you oil level.

I just changed my oil and it went away. Also try resetting your battery.

 

WhiteOnRice, 04-05 EP3s have a 5.5k standing limiter.

 

/\ yep... it's supposed to be a built in launch control

I really doubt that.

 

doubt what?

http://en.wikipedia.org/wiki/Civic_Si

"Performance-wise, the ECU was slightly retuned to compensate for a lighter flywheel, and the launch limit RPM in neutral was dropped from 7,100 to 5,000 RPM."

I have a 2004, it's there... I just highly doubt this is what the OP's problem is

7k "launch control" on an open diff FWD vehicle? LMAO. Besides, 6800 is the rev limit on 02/03, not 7100...

Please don't use wikipedia to "prove" anything. Wikipedia = opinon-pedia.

 

sounds like limp mode to me ...

sigh... look...

they lowered it, to 5K on the 04-05... that's how the sentence is to be read.
and like I said, I own a 04 Si, and it has a 5K limiter when you are sitting still, so I'm not using Wiki for my information, just thought I would show you that I am not just pulling it out of my *******.

 

hey guys sorry for the lack of replies work has been a lil crazy lately.

anyway, yes the check engine light is on.

no im not reving while the car is not moving

no i dont have a CEL

ep3man: 80 on the highway in 5th is about 4k

 

You do have a check engine light but you don't have a CEL? If you're light is on it's like everyone is saying, limpmode. Last time it happened to me it was the O2 sensor.

Not saying it doesn't have it. I'm saying it's not for launch control.

Plug in your OBD-II reader and lookup the code.

I am betting that it will be a P05XX.

Any other warning lights illuminated? Does your speedo work correctly?

Did you check the oil level?

ALSO: 5.5K works well as a launch control. Something about full RPM at idle is bad from the B-series days? Don't know.

 

my car was doing the same i changed sparkplugs and it was coo then 4 days later i blow my motor lol
