Running rough
 

Hi guys. My 2007 starts and runs great, full power etc. Once I turn my car off and restart all the warning lights come on and the truck shudders. I have to turn the key off but when I turn the key again I have to lightly touch the gas to get it to start and it runs like crap after. Doesn't like to go over 50mph, does shudder when I coast sometimes and the check engine light dings. I can put my foot down some and pick up speed but then my check engine light dings when I left off the gas. I did get a code for cylinder 5. I changed the coil pack and all the spark plugs. I am stumped🙁
