I'm trying to troubleshoot a few things right now. Back story:
Last fall there was a slight knocking sound. I had a few spare injectors, tried swapping them with no luck.
Left the car alone for the winter. This spring I installed some L67 injectors, and the intermittent knocking sound is still there, now i'm relatively sure it's a lifter at this point but haven't torn into the motor yet.
A new issue arose. Now, no matter how much I change BPC the car starts, idles ok and then goes rich as hell, to the point that there's unburnt fuel vapor coming out of the tailpipe.
I tried a bunch of things in $8F and bailed on it. I decided to go code $59. I've been having a bunch of hassles in $8F historically and got tired of it, figured I'd start fresh with code $59. I have the same issue with code 59. I adjust BPC vs EGR and it starts great, decent AFR then goes off the chart rich...
Car has good vacuum at idle, coolant and MAT and MAP sensors all working appropriately, and no CEL
Does anyone have any ideas?
Edit: I'm not sure this belongs in Pushrod Performance, but it's larger injectors on a turbo motor so...mods please move it if necessary.
