I continuously have the check engine light come on. when i check the code it just says cylinder 3 misfire. I can go to the parts store and clear it and after a few days it comes back on. the truck can be just idling and then boom the light comes on!! i have replaced the plugs once at 35K it now has 62K..do i just pay the money and replace the coil pack or in doing that will it not fix the problem??

I had the same problem. I took it to the local dealer where I bought my 2004 Cadillac Cts they replaced the plug and the coil charged me over 300.00 and less than one week later my check engine is on again same code.
The engine may develop a misfire due to worn valve seats. This fault will cause the Check Engin...
Check engine light on #5 cylinder misfire on the 3.5 engine
changed plugs and checked compression. 1-155, 2-125, 3-145, 4-145, 5-145. is this enough diff to cause the misfire and would it be the cyl head problem the tsb is about?
The problem has happened before but it would stop after awhile but now is will misfire all the time I do have a scan tool have have not checked the common problems to fix yet
