Okay I've got a 05 TL and whenever car starts it misfires in all cylinders but 3 and quits after maybe 10-20 secs of running. Anyone know what would be causing that? Cannot seem to figure it out.
Also when sitting overnight, when going to start in morning car will turn over for about 15sec then will start

Bad/fouled spark plugs? Have you checked them? Check the wires too.

Check to see if the plugs are getting a spark...which are firing, which aren't?

spark plug and ignition coils, check those two first.

I assume you pulled codes? If not, how do you know which cylinders misfired?

Sounds like maybe low fuel pressure? Fuel pump going bad?

When was the last time you filled the tank?
