I just installed an air /fuel ratio guage ,boost and an oil pressure guage and the air /fuel is just going fromone end to the other rich to lean to rich very rapidlyand when i say rapid i mean RAPID like you can barley see it rapid i was wondering if anyone else has been having this problem with the autometer ultralite series guages , also what are the normal ranges for the boost and oil pressure guages ,mine are between 20 vac and 5 boost ,and 20 to 70 oil , any help would be appreciated . thank you
