I'm looking for some help...my idle fluctuates from 1000 to 2000 rpm especially at start up... But also does its when warmed up and driving. This started a couple of weeks ago.
I've also been getting a bank 1 to lean code going on and off for a couple months.
I had a used '04 L32 and N* installed a few months ago as well...
Any ideas?
Thanks for the help
Vacuum leak. Use carb cleaner and spray the gasketed surfaces and the vacuum lines and if the idle settles down for a second when you spray a spot, that's the leak.
Did you get the appropriate tune for the different TB and MAF?
