Q: Q: Engine Misfire

asked by on

I purchased a pre-owned car and found out that it had a lot of repairs before I had purchased it! My current problem is that it's slow to start, even when it's warm and there's an engine code #6. When it idles, the car kind of vibrates, but doesn't do that at higher rpms. Please give me your diagnostic opinion. Thanks in advance.
