hahaha did any of you guys realize how fast you gotta be going to hit 4K in top gear? I do almost 100 M.P.H. in my 3.0!
maybe you should look there first for answers!

im pretty sure it is a vtec prob. low oil pressure or broken vtec engagemant switch. it wont go past 4k cause the timing above that will advance and the vtec cams "should" switch over. but since they are not switching over it governs it at 4k, so u dont fawk ur motor with the timing advance.

i would have agreed about the vtec until u said it will go past in other gears. just go to a local auto zone, advance auto, etc and see if they will scan it for you.

Great. I was just about to post about this but I found it Well, just last night, I hopped of the freeway, and came to a complete stop. Put it in 1st gear, and took the turn at green. And I noticed something different. My exhaust wasn`t as loud as before. I tried to rev it higher to see if it gets louder, and it doesn`t go anywhere pass 4k rpm. I can hear my intake though. I don`t hear my exhaust going any louder. Usually I would be able to hear the exhaust a lot louder than my intake, but this time when I rev it, I hear my intake, and my RPM`s doesn`t go pass 4k-5k`ish. It`s the same with all gears. And earlier this morning, I took it for a spin, hopped on the freeway, I was in 3rd gear, put the pedal to the metal, it didn`t go ANYWHERE 
I don`t know what is going on.... Please help.
EDIT: Btw, I have a 1999 2.3 CL, 5MT.

its not a vtec problem, vtec kicking in relies on many thing, oil press, and a bunch of other stuff, ive forgotten exactly how it works, but if all the conditions arent perfect for it to kick in it will not limit you to a certain rpm, it will continue to climb the rpms using the "basic" lobes on the cam (it keeps going without switching over to the vtec lobes)
menace - what do you mean by it didnt go anywhere? did the rpms climb and it not go anywhere or was the rpms staying and it just wasnt pulling?

The RPM needle barely moved, when I floor it, it seems that it is trying so hard to get the RPM up. But, I went to a shop today, and told them to check my car for me, with that computer thing. I asked them to check because my check engine light is on. So they checked, the problem turned out to be that I have a "Catalytic Converter Efficiency Low Bank". He told me it was clogged. And that it`s not fixable and I have a replace it..... I don`t have the money for that. What should I do?

I don't think we all gathered that it was only doing it in 4th gear. Most of us assumed it was all the time. In his case, it is not related to vtec.

It`s that cheap?? The first body shop I went to charged me 275 to replace it with a used one. And I went to a muffler shop, and he charged me 600 for an OBDII or whatever.

I got one for my del Slo cause I needed one and it wasn't a cat at all
It was a resonator that had the same dimensions as a cat and same bolt pattern. Fit perfect, but didn't do ANYTHING!!! Actually it didn't even fit all that well, leaked like a faucet! I ended up paying 2 hundred something for a new cat.

Well, today, I refilled the gas, 76, 91 Octance, High Performance I think? Full tank, wasn`t really paying attention to the dash cause I was trying to figure out what the problem was. Hopped on the freeway, I was in 4th gear, at about 3k RPM, then downshifted into 3rd, slammed it, and it hit VTEC, exhaust sounded normal, couldn`t really hear the intake, cause the exhaust was loud as usual. And everything was back to normal. The check engine light went off. This whole thing got me very confused but I`m glad that everything is back to normal at least. It kind of got me thinking that maybe because I had no gas?? I`m on full tank now, and everything seems normal. I was kind of hoping that, whatever was clogged in my cat. conv., flew out of my exhaust when I was on the freeway lol just kidding.

the catalyst inside is like honeycomb shaped ceramic. when it starts to break apart it rumbles around. it may be fine for now but it WILL clog again, they are known to glow red hot and sometimes burn thru the carpet in ur car. and if it cloggs when ur at highway speed. u can say good bye to ur engine. a highflow cat will do u no good cause ur in cali and ull never pass smogg with it. ur only option is to get it fixed or park the car. but ur grown and make ur own decisions.

there is an emissions recall on our cars that cover it up to 100k miles. this includes all the emmissions stuff. check on this and u could have a get out of jail free card, on this.
and techinally its illegal to remove a working cat from a car. even if the car is in the junkyard, so be care ful of the used one. it may save u money but if he has a used one then he's pretty shady.
