Q: Performance issues and check engine light
The minute I got on the highway, I didn't even reach 60 miles an hour and the engine started to buck badly. I just had all the ignition coils replaced and they told me that the spark plugs were all good, because I just replaced them before the one coil went bad. Did they not replace the wires to them? Should they have? The engine light has remained on the whole time. How can I find out what they did or didn't do? I don't trust the mechanic that did the work.
My car has 252000 miles.
My car has an automatic transmission.
