Is it worse on acceleration? Does it seem like it is worse under a load?




This question will remain open and I will continue to work with you even after you accept. The question will remain active for 7 days after our last communication.

worse on a hard acceleration, which would be a load, right?

Expert:  Neal replied 5 years ago.
Yes thats right, bad coils will act like that. The more load the more they fail to provide enough spark. I cannot say for sure without seeing it but that is the next thing I would try based on what it is doing and what you have done so far.
