well i thought it was my spark plugs its not even though theirs black rings around all of them and they are gapped properly.If i give the car gas while starting up it will turn over and then my idle is so shaky its ridiculous. I dont believe that it is a coil pack. So if anyone else has any ideas on what the problem could be. PLease let me know asap. My car was running FINE untill i changed to ngk platinum spark plugs...

 

You need to stop creating new threads for the same problems.

 

All I can think of is to check all connection that you touched and may have touched while changing your plugs.

 

the hard starting could be many things, but the shaky idle, maybe clean your TB? worked for me..

 

Go back over your work, you have an ignition problem.

 

i did, twice. I replaced the spark plugs twice after only having the ngk platinums in for 3 days their is a b lack ring around them already. now i replaced them with coppers and it still does it, do you think i could mess up, twice ?

 

Check out and clean your throttle body and injectors..been there done that, it works...
