Re: Weak spark
If you have already changed everything that produces the spark then the only thing left is the voltage that drives it. Make sure your alternator is good and battery is good. Also check your grounds.
Other than that
What kind of car do you have?
What engine?
What year?
What is the cars history?
How do you know you have a weak spark?
