i know i posted in the maintenance section but i dint realy get any help,when i post here i do i do get great help and appreciate it . I just did a internall combustion clean with GM kleenz stuff and changed my plugs with delco plat.on my 2.4 sunfire gt and since i put in the plugs its runing rough it goes in and out ,like the engine shakes constantly at idle, but drives great .So i changed the plugs again still the same cleaned the spark boots .replace the idi cover with my brothers and changed my egr as well ,no change,any ideals. I by the way also am a mechanic but not a gm one i know a fare bit about them but not enough i guess.So any info would be great .THANKS

Check your plug gaps and make sure that the Coil packs seated correctly on the plugs. It's happened to me about 5 times before I figured it out.

Hope that helps.

what is it trying to idle at ?

motor mounts? you got some mileage in the last 7 years so they could be worn. worth a look

is your sensor in your intake tube or out? i just noticed the larger TB.

i know its not my plugs or cover ,but engine mount i was thinking about it the other day it does seem to move alot more but my car shakes not all the time,but the idle stays where it should be the needle doesnt bounce at all. but im ordering my eurothane mounts anways and well see from there.
