Why does my 2002 Pontiac Sunfire shake while in park?

My guess would be that you have either a bad plug, wire, or cylinder. If its running okay once you accelerate a bit, my guess would be that it is most likely the plug or wire. If one cylinder isn't doing its job, you only have 3/4's of your regular performance. Best of luck. Hope this helps.

I have a 2003 mitsubishi galant ES 4 cylinder and have a check engine light message on i had the code read at auto zone and they told me the third cylinder is misfiring and when it idles it jumps around...

Misfire means you need spark plugs replaced. Or spark plug coils.

That's why the whole car starts shaking because its running basically on 3 cylinders and not 4 as supposed. There is no gas compression on the 3rd cylinder because once again the spark plug is "misfiring"

There also might be even a bigger problem which could be the distributor cap where the coils are connecting outside the engine.
once you fix the problem the check engine will turn off immediately

hope that helps.

1994 pontiac transport se sluggish running

Ck your exhaust pipe at rear of car noting any obnoxious smell like rottrn eggs. Hold a piece of paper, I use a dollar bill ,in in front of the exhaust. If it blows the paper gently, you have a catalyctic converter going or is bad. Will need replace if so.

I change the spare plugs and the car is shaking

If you preformed a tune up I would change the wires too. wires build up resistance as time goes on, and with the replacement of new plugs the resistance is too high so you are having intermittent misfires

2002 pontiac grand am shaking and no acceleration

does your "Service Engine Soon" light come up? If it does get a repair man to read the code.

Have you driven the car for about 150,000Km? then it could very well be that one or two of your spark plugs have stopped firing. You need to get that spark plug replaced. Remember, when replacing spark plugs, it is adviced that you should replace all of them at once.
