Hey gents,
Update: Changed the injectors to brand new stock 550/850cc injectors. The car started and idled but still rough. I noticed that smoke was coming out the exhaust after I shut the car off. (See pic in next post.)
Does this sound like too much fuel? Even after the correct injectors are now in?
The next step would be to install the Power FC and go from there.
Are there any suggestions?
Thanks for the help guys. Appreciated as always.

First off, that has to be the RUSTIEST main cat I've ever seen.
Running rough - was it running rough for a bit and you shut it down, or it ran rough for a long time and the engine warmed up? Could just be a fouled plug from short starts/troubleshooting.

It ran rough for a short time and I shut it off. It did not warm up at all, I doubt it would have anyway. I will check the plugs for sure, just ran out of time this past weekend. Maybe I will try clearing it out as well - fuel pump disconnect and pedal to the floor and cranking it over.
Thanks for your input Dale.

JUst had the same problem, with my 7. Not wanting to rev past 3500. Horrible break up , spurting. Looking at every system, ignition coils, fuel injectors, wringing. Check your crank sensors to crank wheel clearance. Mine where off spec. And when I changed them and got them to spec , it solved my problem. Full free reving , no more break up. Weight off my chest!! Thank you BANZAI!!
