95 jetta putters really bad

I would need to know what the actual trouble code is to comment.

The check engine light is telling you that something has gone wrong with the system. Have the codes read and fix the faulty sensors or parts.

did you check the code,check starter.fuel filter.

need more info etc make model year and so on

You have a vacuum leak. Check PCV hose on passenger rear of engine. Stuck open EGR valve can also be the cause.

the neutral safety switch is probably faulty the radio says safety because the wrong code was entered 3 time key needs to be on for 3 hours hook up battery charger check engine light may be code for trans issue

Remove the flexible plastic tube and check for crack(s) or air leaks.

one small hole on the air intake tube will give incorrect amount of air into the engine.

You either have bad plug wires or water got in the intake like billie said and is playing havic on your mass air flow sesor. Test the plug wires by squirting some water on them when the car is running (we are looking for like a spray bottle squirt not to much).
If nothing changes ( you will be able to tell the car will wana die or you will see them grounding out a bit) then you can try cleaning the mas, or just replacing it.
Also check your air filter while your in there as well might need to be replaced now :)

Good luck

You could have bad gas, Try running some injector cleaner and then chaging your fuel filter after a week of drving. Good luck

it could be a clogged convertor, or theres a potatoe in the tailpipe.
