warning, technical question, step up folks


Recommended Posts

ok, What happens on an EA81 if the thermo vacuum valve (II) has broken vacuum lines? I know it controls something, but what I dont know. It seems to run fine without it, at ~25 mpg.

 

So any ideas?

 

 

Also, while driving home the light conditions were right for me to see a small could of something when I stomped on the accelerator at 70mph and the engine started detonating, it went away as soon as I let off the pedal.

 

thanks,

 

Alex
