uneven idle
uneven idle
ok problem is:
my idle is uneven. it goes up and down about 200 rpm from 650-850.
when i increased the fuel pressure from 35 psi to 45 psi at idle it started to do this. i'm pretty sure this is the reason. now my question.. is this bad? it idles perfect for about 30 seconds then it starts going up and down.

Uneven idle is bad and annoying. Not on the case being severe like lean condition.
When idle jumps a lot, it means your engine is dumping too much fuel at idle. Adj it using your AFC . . . don't increase the fuel psi too much.
I can't remember your base psi should be. I'll ask around.
