Default Important question

My car has 24,000 miles on it, and it seems considerably slower, and when I drive up small hills with the car floored in 5th at 50mph, it actually slows down.. Is this signs of a bad clutch, or could belts slipping do this? If its belts, wouldnt I hear it?

I highly doubt its the clutch dude...Take a look at where you live..
High elevation 50 in 5th gear is really low on the power band too, Im usually in 4th at 50 then hit 5th at about 60.

Well, I bought the car here, and Its actually very slow now. I had a civic with only a fartcan on my bumper that I only shook when I went around a wet/icy/sweeping corner VERY FAST. Normally, I would dust them..

25k, about time for a tune up.
Plugs, fuel filter, air filter, erg valve...
Couldn't hurt.

I have a K&N that I cleaned 200 miles ago, changed plugs with NGK BKR6E-11's 5000 miles ago. I think I may change my plugs, leads, fuel filter, clutch, and flywheel soon. That would make for a nice tuneup

On my car I have a K&N and if I floor the throttle below certain RPM it bogs down. But if I apply throttle slowly, it pulls as it should. Now I don't quite remember what at what RPM that was as I got used to NOT floor it.

With 24,000 miles, the clutch should be OK - unless you pull some heavy trailors.

The problem is you are going uphill @ 50 mph in 5th gear. Downshift, mang!

Also, your "small [Colorado] hills" are like Appalaichan (sp) Mountains.

But the thing is, my car used to accelerate up them faster. If I'm behind traffic and I cant pass, I usually shift to 5th at 50 and just cruise..

well my car isn't stock, but I was trying to accelerate from different speeds in 5th gear. Starting at 50 slightly uphill seems to be no problem at all. Elevation I'm sure is different here and I do have Borla header which does give some extra torque. One thing is you don't want to floor it at a low RPM in a higher gear, just ease into it.. fastest drivers are very smooth... I would definately change your fuel filter. To me that sounds like the mostly likely cause at this point.

Well, Ive had my RS for about a year and 4 months, so I know when and when not to floor it, I'm a very fluid manual driver, and I've only been driving stick since I bought the car. My wife has been driving stick for 7 years, and shes terrible compared to me I'll try the fuel filter, it seems like I've goten this problem after installing a lightweigh pulley, but PS is working like before, my 13.5 lb battery has remained charged, and my AC has to be working, because my defroster still works

I tested your accelereation theory.
5th gear at 50 = slow. There just isn't good acceleration at low RPM in higher gears, even less w/ a high flow air filter.
Left foot to the floor, right hand down and back to the left, left foot out, and right foot down...
The only other thought, is ease into the accelerator, matting it at such a low rpm tends to bog the car for me... shrug.

My car never used to act this way though, its odd.. Ill know soon, when the new clutch and flywheel go in, and all the fluids are changed, my cams and headers are on, etc..

man oh man. it doesn't matter how your car felt before, you are not driving properly. you are loading up the engine by trying to get it to accelerate at such low rpm in a high gear and up a hill nonetheless. this is the same reason wrx people get high egt problems with manual boost controllers because they try to accelerate in a high gear instead of downshifting. you don't have an american v8 so don't do this anymore.

I know I dont have a V8 n00b, Ive had this car for A YEAR AND A HALF! It didn't used to do this, but its starting to now. An this is up the same hills I used to actually pull on.. Theyre not that big of hills. I've only owned 1 V8 and this is years ago.. I had a Honda Accord before this car. I'm trying to find out what is wrong with my car, I'm not trying to be criticized by someone whos car has barely been broken in.

obviously both of us are not noobs. great it might be a problem that its just doing this now, but if you drove correctly you wouldn't have the problem in the first place.

Well, it apparently has to be a problem if my car would pull like mad over these same hills before without even flooring it, but now its struggling when Im flooring it. If I'm crusing behind 3 SUVs in 3 lanes, why waste my gas? I seem to think its the clutch, It feels like its accelerating fast sometimes, but its actually no going anywhere. Is this the clutch? I am a n00b when it comes to clutches, my 93 5.0 and my 98 Accord were both auto..

And also, driving up hills at 55 mph in 5th sint going to cause problems, its from learning to drive stick on the car and also 3000-4500 rpm launchs that do that, and I am guilty of doing that sometimes I also used to have to commute onto FT Carson every morning, which is stop and go, slipping the clutch for 1/2 mile for a half an hour to get on-post. So I do think this is the clutch.

i never said it would cause mechanical problems i'm just saying its always recommend to downshift and then accelerate. an automatic would do the same thing.

Just for fun, what exact grades are you talking about? My RS has no problems holding speed at ~40mph in 5th, but I live in California. I can do that on grades up to about 5%, which are about as steep as it gets. Of course, if I floor it, nothing happens ecept for some ugly intake noise for a while til it climbs past 3,000 rpm. Anyways, I digress. Yes, there is something not right. I'd be inclined to think it's an O2 sensor, or bad gas. You should be under warranty though, so unless you have some naughty bits on your car you don't want disclosed, just take it to the dealer and tell them "it just isn't running strong." They should at least give it a shot to see what they can find. Plus, you have a new clutch coming to you anyway if you haven't already. (The clutch isn't causing your problems- if it were, your revs would be climbing despite the fact you weren't accelerating.)

gas?
Flooring it might be the problem... I know for me, after I did a few mods, air filter, fookin' intake, complete exhaust, if I floor it, It doesn't seem to go. If I squeeze the gas to the floor, ie progressively give it more throttle, it's _much_ faster than straight pedal down. Just a thought...

My cars not happy actually flooring it either, what I mean is progressively push down on the pedal until it touches the floor..

A bad, worn out clutch will start slipping at max torque range - first in higher gears (5th, 4th), than - if you don't change it - it will do it in lower gears too.

If you really have a clutch that bad, you should notice that the RPM will raise fast but the speed will only follow slowly (if at all up the hill). It feels a lot like driving an auto.

I once had a clutch that bad in my old '88 Subie (1800 GL) and I know that it's possible. I just thought that it's too obvious to mention.

If you floor the car, it moves off the closed loop control using the oxygen sensor and into an open loop pre-programmed mode. The open loop is generally pretty rich so it can bog down.
