05 lgt 5spd running poorly after new plugs
 
not my car, but a friend replaced his spark plugs and now the car runs fine when cold or at hyw speeds, but once it gets warm it runs like crap.. sometimes stalling at idle, coils are good everything is connected properly.???? not sure what it might be, anyone?

were the gapped correctly when they were put in?

What brand of plugs? What gap?

I've read a couple posts where the problem was the coil pack plug, they get broken, and/or loose during removal.

You can try reinstalling old plugs and see if the problem goes away. If it does then you know the problem is with the new plugs. If it dosn't maybe a coil is starting to brake down when it gets hot.

Plugs were purchased from dealer, i dont think the gap was checked. But did put original plugs back in, and it ran bad too.

Could be a bad coil pack or bad coil pack connection. We have seen where the coil pack connectors tend to snap when they are removed/replaced to do the plugs.

there is one of the connectors that had already been zip tied to the coil. but the connection is good. still does not explain running like crap once its warm. or only at idle.

Have you checked for any codes. You can start pulling injector connectors to pin point which cylinder is giving you issues,
