rb25 stalls random
So i'm stalling at random times and it only happens when i first start driving. It's when i hit boost for the first time. The rpm's will drop and than i can't rev it past i'd say 3grand without it wanting to sputter(i say around b.c i still have stock cluster for ka in) I let the car idle for a minute than it's fine again..
I figured it was probably just vacuum leak or something with the maf but they both fine. Also, my boost gauge stops at 7 pounds so it's not leaks. CAS is something i don't know much about.. and it's possible mine might be off a hair. could this be effecting this any ideas on top of what i'm already tryin are helpful |

same thing was happening to my rb20 a lonnnng time ago. smoke your vacuum system and make sure there is no vacuum leaks or unmetered air sneaking into motor, also check around intake mani, cause after metal heats up (ie engine warming up) it expands and may seal a slight leak. also rb20 ecus are garbage for compensation. check codes by doing self diag, and lemme know the outcome.
