Ok been reading through the site I have yet to put on an obd2 engine code checker but my mph is like worse than a dodge pickup I am beginning to think it's my coil packs going bad and need reolacig along with spark plugs, it can't even do a burn out cause of the loss of power anyone can confirm my issue? New to this site and new to the cars I have , a 300 and 350.

 

go get codes read, dont throw money chasing something you cant figure out

also why did you double post, so annoying
