ok, i changeds the manifold, edelbrock preformer, and since then its been running really bad, im getting code 43, i think i might have left a ground wire from teh head to the firewall off, anything else i can check, its getting no power, and bad gas milage?

 

Most of the time after an intake swap people have problems with the car because they put the distributor in wrong (like 180° out or a tooth off). I'd recheck that, then recheck the timing, as well as making sure the wires aren't mixed up.

 

how can i check the dist, im now getting code 32 and 43, both related to electrical?
