Good morning boost brothers and sisters. I have a brain teaser for you all. I want to preface by saying, I don't have a powerlogger so I'm just pinging the group to see if anyone has seen this problem, before I dive headlong into this car.
Every so often at a stop light or light part throttle cruise, I will get a lean out condition showing on the wideband of around 17 or 18:1. While cruising, you can actually feel it in the engine, so it's not a faulty wideband and the condition usually clears itself out within 10-15 seconds. Pulls very hard and strong with no troubles. I'm leaning towards something electric or electronic
-newer Turbo tweak 3.5 MAF
-Caspers adjustable cam sensor
-newer crank sensor
-newer ignition coil and module
-turbo tweak chip
Has anyone seen a bad knock sensor or bad ESC module cause this issue?
Possibly intermittent problems with the vacuum brake booster?
The idle never changes so I ruled out IAC
I know Brian Lorenz has told me to get rid of the Delphi 50lb injectors that came with this car but I've never had a problem with them under load.
Thank you all in advance
