I have a 2003 Volvo S40. I just replaced the battery, spark plugs, coils, fuel filter along with a fuel system flush. Because the car was running very rough. It’s been 4 days since i got it back from the shop and now my car won’t start unless I give it gas. The car won’t stay on and it smells like it’s running very rich.
First thing, take it back to the mechanic and ask why its running worse after they worked on it. If you don’t like the answer post back with the mileage and a little history. Best of luck.
