I uploaded the video on streetfire.net but it isn't up yet so ill explain whats going on. My car has started making two strange sounds. I think they are related. One is like a high speed ticking buzzing when the revs come down. It doesn'y matter if its in gea out out of gear. And also this terrible sounding knocking/backfiring at idle. Also sometimes when i start the car a get a little pop out of the exhaust. Any ideas what it could be. I have a video of the idle knocking noise.

video is up!

 

a couple more things. It seems to do it more steadily when the car is fully warmed up. And the engine shakes sort of in sink with the knocking noise. Also you can feel it through the shifter. It only seems to do this during idle. Driving is normal no hesitation and very smooth. Doesn't seem like it's down on power. I though that maybe one of my rotors was blown. But a ghetto compresion test says it ok. Im goign for a real sometime this week. A friend has a testor.

 

That's nasty bro. Hope nothing serious, but **** sounds scary... Sounds internal to me, no clue. Hope you figure it out..
Reminds me of my Camry beater. Fucked up valves.

Nice car too....damn.

 

thanx

 

hey lan noticed your from nj. You going to the bbq on saturday? I'll going to try and take my car there. Well that is if it isn't dead by then.

 

I didn't realize you're from Jersey.
You close by NewBrunswick/EastBrunswick/Freehold/Elizabeth/Bloomfield area? haha the whole ******* town... (those are the towns that Im always around)

 

woodbridge

 

What BBQ? haha
Yeh, I drop by WoodBridge Mall and the one across it, (I cant remember..) Menlo?
Yeh, i drop by there once in a while. I also go to a buddy's ALEX xboxthug13b from Elizabeth sometimes. He lives by Jersey Garden Mall.

We should all hang out. Drink Beer. Don't tell me you don't drink beer too like all I know around here with RX7s....

 

I'm only 18 i cant drink beer yet.. Anyway back to my half dead car.

 

sounds like a washer machine...

 

lean the idle out and it will go away.

rich idles on rotaries bounce like that. i wouldnt worry about the knocking sound, it could be ANYTHING touching/clacking while the engine is moving around with the bad idle.

 

I just replaced my plugs and still crap. Anyone else have any input?

 

how is your timing? Sounds like it's bad timing to me.

edit: pop out of the exhaust when you turn it on would be runing rich.

 

Im restabbed the cas after it started doing this to no avail. I think my ecu is toast after my emop went out the other day.

 

Got a more noiser knock than yours man. Still trying to figure it out. Good luck on yours.

 

From the general smoke you could see with the flashlight..I'd call rich also.

 

did no one see what i posted? the idle is too rich. lean it out at idle and it will smooth out

 

how do i lean out the idle. I have no fuel control?

 

pinch the fuel hose coming off of the secondary fuel rail. lol

 

if the knocking is still bad and you have sometime next week if you want I'll be stopping by my uncle's house, I'm sure you can come and he'll tell you what's wrong with it.

He's worked on rotaries for 30 years now. He rebuilt my engine, 3 times, and ported it ect. He's a shitload of TII's and one I almost shat myself in. if you want I can talk to him and let him know what's up ect. He lives in clifton btw.

Let me know.

 

does it go away when you put the clutch in? throw out bearing? pilot bearing?

 

no it doesn go away when you put the clutch in. it has to be engine related, either that or somthing near the begining of the exhaust. (near the mani.)

I'm clueless since I'm more of an fb guy . Carbed at that.....

 

need a stethoscope like this so you can isolate it

Well anyway. I just took off from the turbo manifold all the back to the mufflers. Checked for cracks and reinstalled everything making sure all is tight. It is still making the above mentioned noise. Could this noise have anything to with the my mop that recently failed? i love my seven nothing else can even come close. I want it back to normal.
