I’m having trouble with my Taurus 2003 and the mechanic is struggling to find anything wrong;
When idling, if I turn on the A/C on the car will start to shudder intermittently. It feels kinda like an engine misfire…
The mechanic replaced the spark plugs and the trouble seemed to disappear but was back again after a number of weeks. When I took the car back the oil-seal was leaking so I got those replaced. It may possibly have been better for a few days [It’s a bit difficult to gauge as the problem is somewhat intermittent] but then the problem was back.
Does anyone have any ideas/experienced anything like this?
