I just installed the above parts at once and have been dealing with issues idling and drivability. At first the fuel pump wouldn’t stop priming. Figured out it there was some residue of protectant on the j3 port. After cleaning that off the fuel pump functioned normally.
Currently, I’m seeing on a cold start the AFR at about 14.5. Once the car starts to idle down the AFR goes up to 10.0 at idle. Car runs terrible aand won’t hold idle. It starts surging. Reading is on an AEM wideband not on the BE.
Once the car isles down and has been running. I give it gas while sitting and AFR drops to 14.5.
I have a base tune I burned to the chip. Tune was provided by Chris at PAS. I’m sure he will build me another tune for base. But unfortunately they’re closed. Thinking this could just be a corrupt tune.
Tomorrow I plan to burn a new tune and see where that gets me.
Any suggestions in the meantime? I ran the car before without a 6 al installed and just installed one. But AFR is still the same.
