ok, every once in a while while i'm driving, my car will just cut power, and if i push the gas in a little, it doesn't do anything, unless i push it to the floor. then it jumps hard, and my car lurches forward with the sudden power gain. it's almost like when you are about to run out of gas, only i'm on a full tank. if i let off the gas when that happens, then it also goes away. i also am having problems with my idle. sometimes when i pull up to a light or put the car in neutral the idle speed goes too low and my car just shuts off. happens every now and then.
