My husband and I purchased a 2011 Mazda 6 2-3 months ago. It had 71,000 mi on it when purchased.
One accident, but only cosmetic.
A few weeks after driving it, I noticed some jerking when coming from a stop and when accelerating too quickly.
I wrote it off as having a heavy foot, but the problem persists. Not check engine light never came on until recently (of course) on our 17-hour drive to our home town.
We had a diagnostic test ran on the car and there’s a huge amount of lost connection codes which we think leads to a bad fuse, an emissions exhaust issue, which explains the revving, and also it needs new spark plugs.
So my question is, by replacing the spark plugs, will we be able to get back home without as much jerking and revving?
