Rough Idle...

[Two Fowty]

Can't find a direct answer in search.

My idle is at like 700 normally, but it will kind of fluctuate from 600-700 when idling. normal i assume?

but tonight, i noticed that my engine was really shaky at idle, and while driving. what could cause my engine to be so shaky? its way shakier than normal too.

the engine would be fluctuating from 600-700, and each time it would dip down to 600 it would give a good shake of the engine, kind of like a human would shutter because of cold weather, and then go back up to 700 and stop, and the repeat. the shaking would go away if i reved up past 1800 rpms. then continue if i got off the gas.

i checked my spark plugs and theyre fine.

any ideas will be appreciated.

i assume it has to do with maf, tps, or something along those lines from what i read anyways, but i honestly have no clue. thanks
