0300 misfire after header install
I helped install a set of dynatech headers, Taylor 10mm thundervolts, and a new set of NGK TR55's on a stock 98 Camaro. The car is running like crap, and giving a 0300 misfire code. After the advice of my local tuner I checked to make sure all the wires were a tight connection, there were some that were loose. So we unplugged all of them and started all over, and it's still giving the error. Anything I could be over looking?

More than likely.. Once when pulling the tranny I got a little oil on the O2 sensors and the engine ran like ****! It is amazing how shitty it will run if the O2 is not running up to par.
