Fix Mercedes-Benz ML 320 Abnormal Start and Acceleration

Here`s the two most possible reasons :

1. Clogged fuel filter/ fuel injector
Its a problem with your fuel management system. your fuel injectors maybe bad/clogged. the fuel filter may need to be replaced.have your fuel filter changed.I would have the fuel system serviced injectors actually removed and cleaned

2. Bad spark plugs and wires
Check for worn plugs and wires

If spark plugs look like a problem , a good tune up and service will be good.
In worst cases, a bad ignition coil could be the culprit too. So check these things

What's more.Your problem is a misfire. You need to do a misfire diagnosis and then correct the cause of the misfire. If you have allowed the misfire to continue for too long, engine damage may have occurred, but otherwise correcting the cause of the misfire should set everything right.
Those are my opinions, hope I can help.

How to Fix "Overheats" of 1997 Chevy Monte Carlo

I think there are five reasons which may cause such overheats.

1. Check the thermostat. Anything stuck in there? It can stick or freeze in the closed position blocking the flow of coolant to your engine. Check the upper radiator hose in it is not convenient to check the thermostat.
2. Check the cooling system. Is there any leakage? Car needs enough coolant to make itself cool.diagnose as the radiator will be low on fluid and there will probably be a pool of coolant on the floor of your garage.
3. Check the water pump. Any faulty? As you said, it will splash water whenever you stop the car, I think it is quite possible that the pump has something wrong.
4. Check the cooling fan. Is yours a electric and mechanical? If yours is a mechanical fan, it will cost you much more time to check the parts.
5. Check the clogged radiator.Over time the radiator can accumulate deposits of rust and debris. If it has something wrong, the function will not stay right.
