On an occasion my Mountaineer will shake and act like it will die

I took it to a shop and they said it was my spark plugs and wires so I changed them and it is still doing it! Any ideas?

My guess is that there is some thing wrong with your fuel system. Try to put a can of injector cleaner in the tank next fill up. if that does not help it start trouble shooting each injector by unpluging it waiting for the engine to start to run differently (only takes about a second for this to hapen) If it starts to run different with the injector un pluged then the injector is ok if the engine does not run differenty the the injector is bad. Also check for vacume leaks, and test your fuel pump

Do you need to change spark plugs on 1999 mercury mountaineer i was told they never needed changing also why would it stall or die when cutting the wheels a little sharp

Yes they eventually need changed. If you never had a tune up your probably due. Plugs, wires ,cap,rotor,airfilter, and fuel filter. All these affect the performance of the engine. Looses power, and can make it stall or cut out under loads, like when you make hard turns and the power steering pump is putting a load on the engine

I have a 2006 Sebring 2.7 L V6 with 75500 miles. For the last few weeks, a few things have been going on. First, AT TIMES, when I start the car, it will have a rough start in the morning and shake a bit....

This is a direct fire ignition system, coils over the plugs. You have never had any code but P0300 Random miss show up? Also do you routinely run the gas tank lower than 1/8 tank, if so that can be the cause.

I change the spark plug and after starte to shake ann act weir and check engine light came on

Did you gap the spark plugs, or did any of the spark plug wires get damage while removing them, or did a spark plug wire get crossed,the engine light is most likely a cylinder misfire, I would check or replace spark plug wire's.

1996 chevy cobolt 6 cyl. "engine power reduced" idols extremly rough shaking entire engine. When pushing on gas pedal car will sputter acting like it wants to die.

It sounds like you have a fuel issue or spark issue. Pull your spark plugs and see how they look. If they look fine then test the fuel pump. You could try to run to fuel system cleaner through the fuel system and see if there is an improvement in idle. Could be any of the following problems,

spark plugs
spark plug wires
fuel filter
fuel pump
air filter

Check the easy stuff like plugs, wires fuel pump and air filter first.

Car dying out after spark plug change

Sounds like either wires are not connected properly, or need new set of wires. More likely wires are installed incorrectly. One other possibility is wrong plugs or installed improperly
