Ok so i just picked up a 86 gxl with a turbo swap done to it... The motor was rebuilt around 5500 miles ago with a extended street port.. When i got it was very are to start and wasn't running right.. after doing some looking i notice the plugs and plug wires were reversed the leading was in the trailing and visea versea... Got them switched around and fixed several vacuum leaks... it runs great now but is still real hard to start checked the timing and set it to specs by the book... still real hard to start.. i pulled a plug and checked the spark on the plug and is very speradict.. not constant at all... I was wondering if this issue is a coil or igniter or what...

Any help on where to go or what to check would be greatly apperciated...

 

The ignitor ground comes from being bolted solidly to the fender so you might want to clean this contact spot.
