So the other day I installed a short route uicp and small battery kit and ever since then my car hasn't been idling right. At first it would idle super lean 16-18 on the wideband when normally it idles 14.7-15.4. Now it will eventually idle at normal AFR's but when I'm coming to a stop or just beginning to idle it will go lean and sometimes want to die then it will go to normal idle. The AFR are normal at cruising and at WOT but the car just isn't idling right... Any ideas? I did a boost leak test before putting the intake back on so I'm pretty sure there are no leaks...

 

Anyone?

 

Have you pm'd Phuong at all?!
