Any advice????

ignition problem maybe? i dunno thats just a guess....can you get it to idle any lower or will it die?

mcinnes

no, at the highest it will be 2 and when its lower it will not die

The_7

when its idling lower does it idle smoothly? can you hear misfires?

Pittdp

your idle should be at 750 rpm

Yes, the fact that it idles at just under 2 grand is an excellent indication that you have issues. Ignition, possibly, but also potentially a vacuum leak. Check your rats nest for a leak. A search should show a few of the more popular methods.
