Just wondering if someone can confirm if there is an issue with my car or if this is normal...
Cold start, the idle is at 16.5-17.9....and then it very very slowly (after about 5-10 minutes of idling) comes down to around 15.5-16, and thats where it stays.
If I try to rev the engine during this time, the AFRs jump off the chart - fuel cut off, going above 18 on my AEM gauge.
Partial throttle cruising, AFRs are either below 14.7 or above 15.0
WOT AFR is around 12.
Stock ECU, no major upgrades, stock injectors, LS2 coils. Not sure if the above is normal or if something is amiss.
Hope someone can chime in and help.
Thanks
