I just got my early 99 runnin and it has been sitting since 09 I bought it without a trans and just got it all together and it started right up and drove great for about a hundred miles then I had an electrical issue with the overdrive switch that killed my gauges and no throttle but I taped off those wires and ran great for a couple hundred more miles. Now I am having a random pulse that is more of a draw then a pulse like im losing boost somewhere. I cant seem to find anything obvious. Anyone have an idea where to start?

 

check all your IC boots. look on the up pipes for soot.
