Yesterday the car started fine, but died when put into gear. I pulled the battery and had it checked; it came back as "bad".
I got a new battery (higher CCA than previous one) and installed it. Now, the engine either won't start (it cranks but never catches), or it does start but runs very rough and almost right away the dashboard message center tells me the engine is running in "Failsafe" mode.
I am positive that I have good, strong connections at both battery terminals and I've ensured that I have proper engine coolant level (the vehicle owner's manual mentioned this may be a reason for running in "Failsafe").
Any thoughts? Thanks.
