The only backfiring/misfiring issue I ever had with my 84 was traced back to a bad cheap Non OEM distributor cap that was cracked and arcing. Check it out!

  Hello, 

         I've got a rough running 84 Westy that I can't seem to figure out. It 
  was running 
  fine until the other day when it pretty much suddenly lost power.It feels 
  like it's running on 2 cylinders sometimes and it backfires on 
  deceleration.It also seems to 
  run hot now.Before this happened,I had changed out my Hall effect sensor and 
  my 
  Hall control module.Van was running well after these changes for about a 
  week,then 
  while driving one day,it started to lose power and wouldn't accelerate.Then 
  it started backfiring on decel and the temp guage started to climb. 
     Any help on this matter would be deeply appreciated.I miss my van as it's 
  now 
  undrivable. Anybody have any ideas on this? 

                     TIA,
