08 cts 3.6 hesitates/misfires with acceleration often and has not started a few times
hi Todd here, I hope I am in the right forum as there are many to choose from. This site uses the same software as I- boats which I use to post questions and answers about my boat anD I like it a lot.
my wifes CTS has been misfiring when accelerating about 80 percent of the time. Trouble codes indicate random misfires. It has had the timing chain recall work done. The plugs have been changed but no coils. Recently on two occasions it would not start. When start button pressed the engine would turn over rapidly but just cough or sputter then stop. After about 8 tries (and charging battery) it would rumble to a rough running state then smooth out. It started fine for a couple weeks then did it again. Been OK for two days now.
I'm not too familiar w di engines but I would swear the problem sounds fuel related. I had a similar prob w an efi engine and it was the fuel filter but I understand these filters are designed not to clog like that.
Anybody got any ideas what to look for as to the cause and do you think the two symptoms are related?
Thanks for any help you might provide
