i got an 87 formula 305 with a brand new rochester comuputer controlled 4barrel.
its very hard starting... when it does start it runs crappy, when i rev it up it stalls/ bogs and dies, making it very very hard to restart. If and when it does idle in park , the service engine soon light flashes, but will go away... there are no trouble codes to pull.... it smokes bad out the exhaust.
I have already replaced the mechanical fuel pump, and installed a remanufactured Rochester computer controlled carb...
what could be causing this? and ideas and help greatly appreciated!!

- Check your spark plugs. See if there are any wet ones (not firing).
- Check your plug wires.
- Check your distributor cap and rotor.
- Remove your Spark Control Module under the distributor rotor and take it to your local autozone to have it check out.
- Make sure you are getting a 12 code out of the ECM.
