New battery, completely drains while car not used for a day. Initial problem car lost power while driving, rpm went up when accelerating but power didn't eventually stalled. Started again, ran real rough, parked it, battery drained completely by next morning, had it charged, started car, very rough idle, put it in gear felt like it would stall little power, parked it, battery drained again, charged it checked w/ volt meter reads 14.4 while idling, put air lights on, engine stumbles, volt meter reds up to 15, down to 13.4ish for an instant, then rippples up and down between 14.3 to 14.9... hope that's clear Thanks 2000 Ford Focus zx3 DOHC

I have a 1994 Cadillac Eldorado and every time i start it the car has rough Idle and the Idle fluctuate's. I also can feel it in the gas pedal when the car is doing this I tried replacing the throttle body sensor but it still does it I also was told it was the Idle error sensor. So instead of spending the unecessary money again I thought I would go online and see if anyone could help me with this problem.

if it has over 40,000 miles on it change the drive belt and have the alternator tested and also make sure all of the vaccum lines are on and in place

SOURCE: engine idles up, down and low while under 1000 rpm

check for faulty vacuum lines

Hi there. Sounds like it could be fuel pressure. Did you try unscrewing the cap on the fuel rail to see if fuel sprays out or just drips? I'd check that first..

2 possible causes:
1. you have dirt in the tank that's clogging the sump when the fuel gets agitated - leaving the engine stopped allows the dirt to go back on the bottom, unclogging the sump of the pump. The tank will have to be taken off the car, emptied and washed thoroughly.
2 - the wires powering the fuel pump go loose when heated and cut off the power - this is easy to test : when this happens just unhook the fuel line from one of the injectors and put the contact(no engine starting), it the pump is still working the fuel should gush out. Clean the contact with wire wool and crimp them a little more.
