Does your idle speed fluctuate or is it steady?

[ljds]

Rpms stay steady

[Pickles]

Sounds like a bad motor mount. Is there any noise when it vibrates?

[ljds]

No noise however when rpms r at 1000 and smooths out

no engine light huh? doesn't necessarily rule out a mis fire, i had one on cylinder 4 and had no light, it would vibrate just like yours and smooth out when i got the revs up, what i would do is make sure all your plug boots are firmly seated, if that doesn't help remove the heat shield from the exhaust header and get it up to temp and drip water on each of the pipes coming from the engine, if it doesn't boil on one, you have a cylinder that not firing.
