okay,,this is what i have changed so far,,
catalic convertor,oxigen sensor,fuel filter,distribuitor cap,rotor,sparg plugs ,sparg plugs wires,

tomorrow i should get the air filter(order), did not find yet the air pump filter!,,
-fixed the timing at 0.05 ''

now for some reason my car when is cold ,,the rpm goes litlle up and down ,,like the transmission is going back in foward when is in parking!,when is hot is okay,,,weird,, it did not do this before,,,maybe from the gas?,,i filled up with some 89 instade of 91!,,

any sugestions on this will appreciate,,
thanks in advance
