Perfectly good running car until yesterday.

The vehicle was 2quarts low on oil and I
Drove it to the auto parts store with hesitation on take of intermediately. Got the oil in and it wouldn't start got it towed home investigated and discovered a clogged fuel filter. Replaced it and it will only start in neutral and when put in gear it stalls unless the gas pedal is idled up. And there's a rough take off and it's smooth once it gets going. Stalls in reverse automatically.
