Please help, Engine doesn't rev over 3000 RPM

[mzk784]

Hi all, I am a new S2K owner, just got the car 5 days ago, I hate to introduce myself with a problem, but it just happened today.
the car was driving great and i was revving the engine just over 5500 and suddenly the the check engine light went on and felt like I run out off gas, the engine doesn't rev over 3000 rpm any more and feels like its hitting a rev-limiter or ignition cut off. luckily I was able to pull over to the side of the road and stopped the car. turned the engine off and on again. check engine light still on, but I can rev the engine back all way to red line. I drove the car again and if I try to rush the engine (5500 to 6500) the problem happens again, and engine stops reving over 3000. same; turning engine off and on would solve the problem temporarily.
the car still under factory warranty, but I coudn't get an appointment earlier than next week for repair..
can anybody help please ????? is it software problem or somthing wrong with the engine ? can I drive the car to work or I should avoid driving it ??

I would'nt drive the car till it was looked at, that sucks sorry to hear about that

yea dude best bet is to carry it to the dealer since its still under factory warranty and everything.Dont let the dealer give you crap most are really good but if you run into trouble best advice is just to go to another one. Sorry you haven the bad luck with you new car man but welcome to the site!!

Welcome Mzk ! It's nice to have you aboard but sorry your intro had to be with a prob.

You said you're a new owner of an S2k -is the car an 07 ?

[mzk784]

It's 2005 with 22000 miles on it.

I would think just for safety reasons alone you wouldn't want to drive it till it's fixed. I mean, if you can't rev it over 3k what kind of accleration would you have? Each shift has to be abreviated. Not good.

tighten your gas cap...the reason the car won't rev over 3k is to prevent damage to the engine when there is a problem. The most common problem is a gas cap that is not tightened...turn it until it clicks 3 times...and if that doesn't solve the problem...you still have the dealer appointment.

check all your sensors. when i adjusted my valves i forgot 2 plug the crank shaft sensor in and i ran into the same problem. check your cam shaft and crank shaft sensors. if the engine gets an improper signal from one it will run on limp mode. if both of them go out it won't run at all because it won't have anything 2 signal the sparks.

The gas cap should not cause the rev limiter problem just the check engine light. I had the same problem with mine it was caused by some wiring I did with my supercharger.

thats ok that it is a year old. but look at it this way. someone else with the same problem could come along and see this thread and be like ok well that dosn't help read down see what i posted and be like awsome now i have someplace 2 start looking! the porpus of these fourms is to help eachother out threw experiance. some members arn't as mechaically incline and don't know how all the different sensers would affect how the engine runs and what happens when they malfunction.

yea maby my reply wasn't soon enough 2 help the OP out and he might have paid good money 2 get his car fixed but that dosn't mean i can't help someone in the future!

I don't see what any of this has to do with mammals that live in the water.

It actually sounds like the v-tec solenoid is unplugged.

[fatality122887]

idk on my buddy's 2000 Si when his Vtec solenoid shit out on him it reved all the way 2 redline the cam just wouldn't change over. idk if ours is set up any different. but if it has any effect on the rpm being limited it would probably limit it at the cross over not at 3k. but i'll unplug it and find out what it dose and report back later.

Im pretty sure that is incorrect. IIRC, If you unplugg the cable going to the solenoid in an S2000, it will not go over 6000. His problem was it would go over 3000, so it could be a combination of problems.
