Owned 76 2.0 for two weeks now.
Lots of little jobs completed. But I have an idle that’s 1100 rpm. The idle screw is virtually fully in. I suspect the AAV is stuck slightly open when engine hot. If I pull the tube from the air intake and put my thumb over it, the revs drop to about 600 rpm. Everything else is good. All hoses correct and no leaks. Am I right in thinking the AAV should close up completely? If it’s a stuck AAV, any recommendations for getting it freed up? Cheers. Gary |

Many thanks. The drop to 600 rpm I think could easily be adjusted using the idle screw on the throttle body. At the moment, its almost all the way in. The timing is correct - along with no vacuum leaks the best I can tell.
I'll remove the AAV, and try and get it to close fully - but the soaking and cleaning method. Hopefully I don't need to pry open. Appreciate the quick response. As I newbie to 914, I'm just finding my way. |
