"Just picked up a 1994 850 wagon from a drunk guy for 200 bucks...and it has a weak spark and will not run....I have an inline spark tester that if i take a plug out and connect it all together laying the spark plug on top of the valve cover it has a healthy spark, the tester and plug. Put the plug back in with the inline tester and it barely lights up? My guess is i got a grounding issue some were. I also read it today...but i can not find the post. Are these cars know for bad grounds? i just wish it was a turbo model...lol



thank you in advance!
