I just spent 1300$ having my car in the shop for random misfires. it took 23 days to get back and theirs no large difference. i have now checked and replaced the following. ignition coil, plugs, wires, fuel filter, 3 injectors, they drained my tank and put new fuel in it, another new fuel filter, mas air flow, re flashed ecm by dealer. the car drives fine 90% of the time then chokes and stops firing. i cant afford to send it back in or stand driving it this way. any ideas. im now thinking fuel pump or fuel pressure regulator. should i try this myself?
