hesitation....940 900

Doesn't happen very often but I'll giv her gas and she hesitates. Actually, stalled a few times. It's more of a problem during local driving. Someone suggested using higher octane fuel. The car's idle seems a bit low---- related????? thanks gang....sbdski

    hesitation....940 900

    Going through some old posts . . .

    Had this exact problem with a 240. Cleaning the Idle Air Control valve (IAC) cured it. (Or it could be your throttle position switch (TPS); your IAC won't kick in/out correctly if it's not switching).
