Try removing the egr valve and cleaning it thoroughly.It has 1 electrical connection and 1 vacumm line going to it and is held in place with 3 ten millimeter bolts.It is located directly below the carburetor on the passenger side.When removing it note where the metal gasket on the part is place exactly so as to reinstall it the same.And use either brake cleaner or carburetor cleaner and a toothbrush to clean the build up of carbon out and even sand paper or a brush on a cordless drill does great.Unless the emissions side of things are in need of maintenance like the breather style filters in the air cleaner housing that feed into the the charge air pipes or the exhaust collector which is directly below the exhaust manifold is clogged up with carbon (a real possible).Start with the above,if no change to do the collector job it does require some time and recommend removing the exhaust manifold and disconnect the exhaust piping below from where it comes from the convertor to be able to remove the collector.To clean the collector which looks like the size of a mayonaise jar (I soak it in muractic acid in a clean paint can over nite)use GLOVES and then pour some baking soda inside to neutralize the acid and blow out with a air nozzle or let air dry for a good while.This will make a HECK of a difference on the trucks breathing especially if it has never been done.Hope this this is not a overwhelming amount of information but,will clear up the problem and I speak from 23 years of owning my 87 bseries since new.
