Hey all,

Just wondering, on the -SE's 13b
it idles fine then every once in a while it 'pops' . the engine moves and it can be felt inside the car.
I don't know what that could mean.
Also at times it's fine, then the rpm's jump..up sometimes 1000 rpms.
Remember this engine was over heated. No oil in the cooling system,no water in the oil, pull the lower plugs,
nothing !! My thinking is that the o-rings were toasted by the over heating. The cat. has been punched out so there's no back presure, and the car is load.
Yesterday i flushed out the cooling system, forwards, backwards. And i used that stuff " purple power " degreaser to flush with, that **** works awesome !
