Drove to a store, when I started up my 2005 MR again, the idle was bouncing from 1k to around 400 RPM. My AEM wideband was reading 10-11. Started driving and fhe AFRs were stuck at 10 for the most part. There are short periods where it would go back to around 14.7 but then it would just go right back to 10. The car seems to be running fine while driving, but at every stop it wanted to die on me. I didn’t try to get on it. Only built probably like 5 psi max on the way home. I’m on E85, speed density, and have brand new spark plugs. Recently did a boost leak test and found nothing but the biss screw leaking.
