Ford Taurus 2002 SE 3.0L V6 - Vin:U
No check engine light. Only light on is the battery
1st Problem - Car Battery
When I drove the car to this restaurant to go deliver the food, the car was running fine even after pickup. But once I deliver the food by shutting my car off, the battery light would stay on and would stall in 2 seconds when it reached 1100 rpm and that was always the result. Waited a few hours the car started up the rpm rev high and the battery light went off but when we turn it off again the same thing happen over again were it would go to 1100 rpm and stall in 2 seconds. Also even when i try pressing on gas pedal while i turn it on it just quickly dies it wont rev up. Next Day I go there again while it was sitting for good amount hours. I turn it on the car kept reving up and got to 2500 rpm before i shut it off. Waited few seconds turn in on again and luckily it stayed on so i could get it home. Once i got it in the driveway i tried turn it on again but this time it would do the same thing as before rev to 1100 in 2 seconds and die even if i press on the accelerator it wont rev it up but die quick or even changing gears just the same result dies quick. Always had a issue with the Remote start were it will work and not work, put new battery in the remote and same results. Took the remote starter box out and still resulted same with the car battery.
Checked it with a meter the alternator was funky so i replaced it. Still the same results. Eventually after dad did something to the wires by the fuse box the car would turn on but still had to jump the car many times when ever we turn it off. Car revs up to 1500 rpms then shifting gears it goes to 1100 rpm. While shifting from reverse to drive the car would rev the rpm up quick for a second to drop back down to 1100 rpm. When putting in park it goes back to 1500 rpm.
Replaced the Battery and the battery light remains on. car still goes up to 1500 rpm then after letting it sit for a bit i was going do a test drive on it but the car is back to square 1 rev to 1100 rpm an 2 seconds later it rpm drops and stalls. Checked all the wires and fuses but there good everything is grounded right.
Second Problem - Black Smoke and other
I changed the head gaskets a month ago did everything right to it torque specs and gasket sealant. When taking out the front middle New spark plug there was allot of combustion on it (Today), while looking at the valve stems back when i changed the gaskets there was 1 black 1 grey. It sounds like it misfiring when the coil is good, the spark plugs were changed. Rods are aligned. There is no vacuum leak either. Also after i changed the head gaskets 4 hour driving in there was knocking noises but when i got it home and added more coolant in it the knocking went away and have not came back since. From the exhaust pipe it blows the black smoke out but it wasn’t doing it when i was getting it home that one day when i got lucky
3rd Problem - Coolant Boiling over
Reservoir cap was changed a year ago, While changing the head gaskets i put a new thermostat in it. Changed the idler pulley and tension pulley also. A year ago I put stop leak in it and then few months ago i been always having problems with the car reservoir boiling over were it spits out of under the cap of the reservoir. We put a pressure Gauge on it before the head gasket change and it kept building pressure.
The fans spin on the car.
At this point I have no clue what to do. I literally been trying everything and had other mechanics look at it but they dint know either.
