Default "93 4.9l idle
I am having what it sounds like a stumble in the idle? I am posting a video of my motor running..Hoepfully someone can hear what i am hearing..
I didn't get any trouble codes.Except when running the 213 spout code came up. i have the spout in. I replaced the wires and plugs and cap and rotor.i set the timing at 10.
Thanks for any help!!!

What did you gap the plugs too? Mine were gapped to large and was making it stumble occasionally at idle

Agree with checking the gap on the plugs, also try cleaning the IAC valve and TB, as well as hitting the connectors with some QD Electric Clean.
