Cheap annoying idle 700 1985

posted by  someone claiming to be John K on  Fri Nov 10 18:13 CST 2000 [RELATED]

Hi,

The idle on my 740 Turbo is cheap. It is a bit rough, and the needle goes up and down a bit while idling. I've cleaned all of the hoses, replaced Air Mass Meter, new Turbo Down pipe hose, pretty new CIS/IAC motor..... What else can I do !? Would the fact that it's only getting about 19.5-20 mpg with 92-94 R+M/2 octane gas?

    higher octane gas won't get better miles, just less knock.

    or at least, so I'm told.

    gasohol is nice, but volvo says "no, no" to its use.
