jumpy idle

Hi everyone-

I had an interesting problem pop up on the way home today. My FD starting having the idle starting bouncing from 500 - 1500 rpm's whenever I was at a stop. Has anyone ever seen this before? My 7 just recently spent a month at Rotary Perf and has been running lock a top. It's all stock, except for its vmount IC, Apex intake, exhaust, downpipe and power FC...

Could I have some bad gas in it?

Thanks,

Dan

We've been discussing this issue for a while here:

So fa, no one's come up with a cause for the idle surge.

That's not true, there are LOTS of reasons for idle surge. TPS not adjusted right, ISC needs to be cleaned, bad clutch switch...there's quite a few things and it's well documented.
