tonite after driving around w/the dump open i put it back on and noticed in park i rev it up and it almost dies then gets back into a normal idle. and suggestions as to why it does this? i had just rewired the fuel pump hotwire through the passenger compartment and had to disconnect the battery to do this so could it just be re-learning the chip?

thanks
