Hi Guys,

I had the 440 in my '71 Charger rebuilt last year. I didn't drive it a whole lot, but it ran fine.

I started it this spring and I am getting an erratic idle.

It's set at about 900 rpm, but it dips and revs between about 750 and 1,000 rpm as it sits there idling, and sounds terrible when it starts to idle down.

If I put the idle speed up to 1,100-1,200 rpm, it seems to mostly smooth it out, it might fluctuate 100 rpm, but not 250-300 rpm like it does at idle.

The car sat all winter without being started. I am wondering if this might be a vacuum leak, or what other possibilities might be.

Thanks for the help.

Greg
