It's the fuel line that is kinked, the vacuum hose it fine.

 

does it act up when you're drivin, like vibrations driving? my car makes a lot of vibrations if it's sitting with the clutch out in nuetral. then smooths out somewhat after being put in gear with the clutch in.

 

Sitting, Driving, clutch in or out, in gear or not it vibrates, you don't really notice it at idle but once you get to 2,500 you can tell it's there get's pretyt bad at 4k, but I am not running the motor over 4k yet.



But I still don't know for the life of me why it would be glass smooth when it's cold. I will be fixing that fuel line, replacing the fuel filter, plugs and wires here shortly.

 

Are you sure the counterweight that came with the alum flywheel is for an S4?

 

my car did this exact same ******* thing all last year.. mysterious vibration that would sometimes go away, sometimes not..

I couldn't figure it out for the life of me, still haven't... hopefully its gone when I put everything back together this year.

 

If I remember right the part number that came with the counterweight was the S4 part number.

 

OH MY GAWD!!!! I took some advice from a friend on the RX7club (BlackRx7, thanks A LOT if you are on this forum as well!) and took off the crossmember and remounted it. AND IT FIXED IT, HOT DAMN!!!



I just took it out for a and the vibration was gone, holy **** now I just need to finish up a few odds and ends and put this bitch back on the road.
