Idle hunting after system install

[roscoe1972]

I installed two modest (400wX2 rms) amps, and my idle started dipping and would bounce when I would stop. It's a manual *****. I did the big3 upgrade thinking it was a voltage issue but it didn't help.

It is intermittent and will stop for a while, but sometimes feels like it will stall. I pulled the fuses from the distributer block, cutting off the amps, and this still occurred.

Any help would be much appreciated.

Wait, the idle still dropped when the amps weren't connected?

If so, then it's not an amp issue probably. And I can't help you.//content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif

But, my car also used to bounce RPM's when idleing, and once it stalled, when the bass was hitting really hard. That was because of my amp though.

Now I'm getting a new alt, hopefully that will solve the problem

ECU connection to the battery isn't tight? Cold weather?
