Ok, well I'm not having a big problem with the car at all, car runs fine, besides the idle when the engine actually warms up.

Which is a little issue, as I heard crx "si's" should be 500-700 rpm at idle, while mine rests at 300-400rpm which 400rpm is an "HF" idle, and besides that I get a little surge every now and then at that low rpm.

What I mean is, the rpm will go up and down every second from 300rpm to 600rpm. Like you can hear the engine do this, slow to high pitch sound.

Just to add on top of that, I got a engine swap with a b16a. It runs nice trust me and I really wanna keep it that way.

I heard vaccuum leaks are the issue to surging idle. Which I have two but I found where 1 goes, I just need to figure out the other.

Here are some pics.


Heres a more far picture so you can see what we're looking at and where its hooked up to. The circle one is hooked up to the throttle lever, you know the thing you can press against and it'll make the engine go VROOM VROOM. Basically what the pedal does. It appears to be some kind og plunger valve mechanism looking thing but it does not have any vacuum out of its line (Where I have the yellow cap installed is the vaccuum line)






Any idea why it has a vaccuum line, and it doesn't work? I put a cap on it anyways.

The other vaccuum line next to it that I mentioned goes to the air filter. Gonna see if I can just purchase its own little air filter.

----------------

Ok now, for the water leak. This is what I don't get, everything in my car is dry. seats, dash,you name it and tis dry. ONLY in the driver side floor, everytime it rains, there is a big *** puddle.

And when you feel every other part of the carpet that extends higher, like behind the foor pedals, next to the center console, they're all DRY, no wetness, besides the very bottom floor.

I heard a guy fixed this problem but I don't understand what he means

"It seems as though the water stays in the rockers and then flows in when i move the car.

Well as we already have established the doors are supposed to allow water through them. There is a small black rubber cirlce on the rocker that seals a small hole. Mine seems to have come unstuck.. i will super glue this shut and retest the water leak.

i glued and sealed up the circular black rubber seal on the rocker panel inside the car. I dont get any water coming in the car anymore. "

Any help is gladly appreciated if anyone knows or has had these problems before. I just want everything to run normal as it should, and no vaccuum leaks, etc.

 

injectors or distributor

 

If it were my injectors or distributor, I wouldn't get getting fuel at all nor spark, distributor is just an open close switch. It either does work or doesn't.

My car runs fine, its not like its not getting fuel, in allr eality, it smells a little rich on fuel.

I really need help identifying the vaccuum leaks, not just random guess's with no back up info.

 

Try the IAC valve..fixed the problem on my car.

I'll definately check it out. I know that definetaly has to do soemthing with the idle. I'm just kinda worried about this throttle thing thats lingering under my hood.

Because the iac valve controls the throttle on idle if I remember, and that plunger thing is hooked up to the throttle lever by the adjustment screw (not sure if mine has the screw, gonna look tomorrow) and I'm wondering if this thing is whats making the idle so low.

Its a possibility, cause it ain't hooked up to nothing. So it could be messing with the idle control stuff, if that makes sense.

 

My bad, I think you may be on to something, cause it bypasses the throttle for idle speed.

But no one knows what that plunger thing is at all?

Its called a dashpot and it just keeps the throttle from slapping closed when you let off the gas, if its capped it should not cause a idle surge. I would trace all of your connections, depending on what gen that motor is there maybe one or two on the back of the intake mani that get missed alot. Also check your break booster vaccum lines, those crack alot. Good luck

 

But why does it have a vaccuum line? And where would it plug into, thats the whole question here.

Ever since I capped em, I don't get a surge anymore, but my rpm rate is still too low for this type of motor.

The idle control system should keep the idle a little high so the lifters don't tap around all over the place.

Oncemy engine warms up, and then finally hits the low rpm, I get a lifter tapping. Which it should not be doing at all. When I rev the engine 200-300rpms off from 400rpm = 700rpm. No more lifter tapping.

I'll definately look behind the intake mani, but did you mean the power booster? I'm sure thats all plugged in, or I wouldn't have any breaks. But I'll check anyways.

 

Check your coolant.

 

Ah well, I just checked everything out, no cracks everything appears to be hooked up from behind, sensors, etc.

My battery needs to be replaced thats for sure, but my car is idling at 600rpm pretty much warmed up. Thats good news.

My vehicle isn't ABS, but I got a brake light on. Its been there since I got the car and it had a master cylinder issue that I replaced and its fixed and everything brake wise works fine.

How come the light is still on? The reservoir wires are attached and clicked.

How do you reset the brake light on a OBD0? I had my ecu chipped, and I wonder if reseting it will reset the 8000rpm to normal? Which is not good.

Also I noticed my fan doesn't come on, the radiator fan. It worked when I got the car, but is there a way to test the fan?

I heard also theres a sensor that controls the fan.

Let this rookie know whats up, I really need some detailed info

 

Coolant is good and green.

 

random guesses? lol learn about cars buddy, if your car bogs, your car is trying to get fuel to accelerate, i had this problem, and made sure they all were plugged in, one was loose, fixed my problem

 

Vice versa, learn to read, think before you talk about anything including cars.

My car doesn't "bog". As I said on the top line, car runs fine, but gets a small surge on "IDLE" everynow and then, NOT WHEN ACCELERATING, if you have read earlier, it fixed the problem putting the caps on.

The low rpm hasn't occured yet, with my luck it might.

Wasn't ******* you down, but this thread ain'tmet for ego's. Keep it to yourself, and thanks for trying to help, for reals. All I know, it could be that, but the engine doesn't have very much miles on it.

 

lol still didnt fix the problem yet huh?

 

Yeah both vaccuums hooked up to the intake piping. No more "little" surges.

lol any more questions huh?

 

lol
