This is a welcome section, I have moved to where youll get more attention for your question. Welcome to the forum btw!

 

ok welcome to the forum. i have a couple of questions. did you have the right o2 sensor hooked up or installed at all? ( i believe it should be a 4-wire o2 sensor). that could be a cause. did you swap over to the right ecu or swap ecu's at all? did you switch from dpfi to mpfi? if so did you hook up a resistor box?
