hey i have an issue but dont know exactly what it is. first whenever i start my car usually the rpms are high because the engine is cold. well my car revs up for like 3 seconds and then the rpm drops all the way down to were it wants to turn off. also once the car has warmed up i hear the rpms fluctuating high, low, high, low etc. i was assuming it was a vacuum leak but i cant find it. and lastly while driving the car with a full tank of gas mind you, it just seems bogged down. its like no matter how hard i push the pedal it accelerates at the same speed, unless of course i completely mash the gas pedal then it chuggs on up to speed. im thinking all are related maybe fuel related at that. appreciate the help in advance.
