My car is stuttering going down the road and the guy at Auto Zone said it sounds like the IAC valve but I don't see how that would be
If the issue occurs while you have the gas pedal depressed any decent amount, the IAC is not the issue. And if it idles well, hot and cold, the IAC is not the issue.
Well while I was replacing my clutch cable, out of a hunch i decided to see if my dizzy was tight and it turns out it was fairly loose. So i tightened it down and so far so good no stuttering or pinging yet. I guess that could have been the problem?
