I just changed my plugs today thinking that was the cause of my roungh idle, hesitant starting, poor running, ect... when I noticed two of my plug wires were switched on the coil packs. Cylinders 1 and 4 were reversed. As soon as I switched them, all those problems went away. I've not been able to road test it yet but I suspect I will have more power than I did before.
GM replaced my LIM gasket a while ago, so they screwed up.
It's been like this for a number of weeks, is there any damage that could have occured from this? It kind of ticks me off...
Thanks

The only damage that I can think of is maybe a couple of fouled plugs. And if it's running ok now, they should burn themselves clean. I guess it could have taken a bit of life off your O2 sensors and possibly your cat, but since it hasn't been running that way for too long so I doubt you'd be able to prove it was the problem if they need to be replaces 4 years down the road.
