Hello,
yesterday i tried to do a ghost cam on Sierra 4.8L 2006.
with 2 tables only
Spark - Advance - idle adaptive spark
Overspeed & Undersppd tables
i did rise the values in both of them and the car idle nice with a good sound for cam and everything seems normal.
but i got check engine " Random misfire code " after few min. and it's not stable ( check engine light flashing )
the check engine disappear every few min and it get back.
Can someone tell me if im missing something here. Is there a tables which need to be adjust?
thank you in advance
