Running rough, blowing smoke and dumping fuel out the tail pipe.
My mechanic says I need to replace my ECM.
Any thoughts?

Pull fuel rail and turn key on, don’t crank. See if the injectors are leaking. Could be time for plugs and coils too. I’ve had good luck with bravex ignition coils from Amazon. But oem are best.
