Title: Low speed miss
Post by: SnPaC on November 24, 2008, 03:21:06 PM

While driving the car at cruising speed, but not accelerating, I will get a slight hesitation or “miss”.  The car will then resume back to normal.  Just today, it stalled a couple of times as I was coming to a stop.  Under acceleration or WOT, there is no hesitation.

What do you suggest as a starting a place?  I did check the vacuum lines a few ago while looking into an emissions failure (turned out to be the cat) and they were ok, but they could be bad now....

I'd check the vacuum hoses again, and the intake boot.
