Hello I’m having issue of a code p0300 random or multiple cylinder misfire detected .
First off I have fixed all other issues posted in past .
The car has been sitting for a month with gas that is maybe a little older .
It is parked due to none payment of registration so I had to put a non-op on it .
When I parked it it had very little gas in it . Ice has formed on the car sinced parked .Could this be bad gas ? Or is there another famous Pontiac problem ?
Any help would be greatly appreciated thank you.

Could be several possibilities:
Bad fuel
Bad fuel pump (suggest you check fuel pressure)
Clogged fuel filter
Faulty fuel pressure regulator
Clogged or faulty injectors
Faulty ignition coils
Faulty ignition wires
Faulty spark plugs
Faulty crank sensor
Faulty injector signal
Vacuum leakThis list can go on…
You need to start narrowing down the possibilities.
