but seriously, might be spark related, if that intake tube is metal your coil wire could be arching on it.... this is one of those annoying problems that can be either really easy once you find it, or a nightmare...
I seem to have pretty much the same problem just not as pronounced, mine doesnt happen as much since i did the timing belt....
BTW sick looking truck... needs a the Total Chaos suspension treatment
