my 97 is shaking whole truck at idle?

[chevyboy34]

when my truck is ideling the whole truck vibrates or shakes side to side. I thought it was just because of it being cold but even after i warm it up at idle it goes back to shaking! I was wondering if water in the fuel would do that or maybe my fuel filter needed to be changed? It just started this as it started to get cold. I live in wyomng and its been non stop snow the past three days? thanks guys

Could be a bad injector/missfire or a dual mass flywheel coming apart if it is a stick. Or possibly a burnt valvecover gasket causing one of the injectors to not get power.

Might want to think about a bad Cam sensor possibly if it's running bad
