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.
The fuel pressure may be low and the vibration could be caused by bad motor mounts, if the engine does not have a misfire.
Have the vehicle’s vibration diagnosed by a qualified mechanic to address the problems you are having.
