I changed :

Rotor
Cap
Wires
Sparkys

and my teeth are shaking like a **** when i'm at a stop light. I think my car idles too low, or it could be the timing. It runs great over 1k rpm,

I'm changing the timing belt and water pump tomorrow (much needed maintance w/102k miles)

anyone ever experience this?

 

Check your vacuum hoses...sounds like a leak...

 

ok i got a crack in one of my hose... i'll check it

 

any other possible causes? i have the same problem occasionally. shakes like no other....like its about to stall.
