hi. yesterday my car was running fine. then i checked the oil and it was half way down so i topped it up.then today when i try to start its running rough and when u try to put it into gear it stalls. the only way to get it into gear is to just put it into drive without using the break. after its in drive theres no problems at all. is there a loose cable or sumthing or could it be worser? also when u put it in gear the revs just drop and it stalls. same if u put it in park. the engine just dies
