u need teh vtek oil

a clogged cat gradually gets worse once it starts, but it's not something that will limit your rev to a certain rpm

Thats exactly what happened to my car when the cat was clogged.

i know

but the OP is stuck at a certain RPM, thus it's not a clogged cat haha

sounds like a clogged cat

True... try pulling the exhaust off (before cat) and drive it open... if problem persists, clogged Cat.

LOL... vtek oil - actually, low oil level will cause your vtec solenoid to malfunction and vtec won't work and engine rpms will fall on its face too. It happened to me once. Got on the fwy onramp, hit the gas, full throttle and it hot about 3500-4000 rpm and it made no power... checked oil level (cause I knew it was leaking) refilled it and ran like a champ after!

GOOD LUCK!

im with nasohc .i have heard many people asking about this it eneded up being low oil vtec solenoid malfunction .but they had to change the vtec solenoid to take off the check engine on there car .run the codes no guessing codes with tell you everything but sounds like car is in limp mode to vtec solenoid

OP, you have a CEL on right?...i'd think common sense would say to check that first as that light is there to tell you something is not working up to the ECU's expected limitations. Also check your oil level as mentioned already.

If someone hasnt said this, Check your oil, also check your vtec solenoid. My did that before. Haven't gotten a new solenoid yet but just keep an eye on your oil if you can't get the solenoid yet.
