Default Engine issue

I have a 99 ranger 4x4 auto trans. Yesterday I changed the plug wires I had changed the plugs earlier, when I started it it was running ruff, no power and the idle was surging up and down. I checked the wires all in the right position. Checked for a vacume leak nothing. I pulled the IAC no issues I had just put it on a month or so ago. I disconnected the battery and let the computer reset no difference. I evewn put the old wires back on. I am at a loss does anyone have any suggestions? Is the coil pack bad?

Thanks

Even if the plugs are pre-gapped, always check them in case the stock boy dropped the box.

Yes the plugs were gapped properly. I have been working on cars since 1970, I know how to change plug and wires.

Coil pack diagnostics info link below. Didn't see any mention of testing ohms off the bat, but I know that is one thing you can check also.

Not everyone knows that and hasn't been working on vehicles long if at all. That being the case, we try the cheap easy stuff first and go from there.

Sorry if you felt like I was insulting your intelligence or mechanical ability.

Thanks for your assistance I found the issue it was a vacume line off the back of the intake. Put the line back on and it is running fine. Thanks again.
