Re: Having trouble getting truck to pass emissions hc`s...
Try setting the timing several degrees less that what it calls for. The car may run a little sluggish, but it might have a better chance of passing. You can move it back where it belongs after the test.

When was You're last Tune up?
Check the Spark Plugs to make sure the Gap is correct. HC is unburned fuel ,Check the Air filter and Replace as necessary,If coil over plugs Make sure to replace the Boots on the coils as they have a tendency to Bleed and wont show a trouble code.otherwise Change the Spark Plug Wires this should Clear You're Problem
I would replace CATalitic converter, this car is old, plus a tuneup is 100% necessary , spark plugs wires, ditributor cap & rotor, plus both the air & fuel filters need replaced. change oil & filter. then you will pass emissions test. and your car will run like its suppose too. if you don't do all this , then buy a new car !
