Need help ASAP please!!!
Ok so Let me start by sayin, I have read and googled everything about this but i have yet to find something that relates to my issue.
Now I have a STOCK 2000 LS1 A4 with ls6 manifold, truck coils, and ported throttle and tuned on HP Tuners on my 240sx. The issue im having and it started over night is this.
When i go WOT or just rev the motor passed 5000rpms it goes SUPER SUPER RICH from 11.5 to the 10.5 AFR. Now i dont hit a wall when this happends BUT it does break up all the way through the rest of the revs to 6500rpms.
What i have done so far. I have changed wires and plugs.
I have a log of the car on a WOT throttle i will post tomorrow.
I also opened the valve covers and the springs/retainers are not broken, and pushrods are good. But it does not feel like valve float but i could be wrong.
Car has no DTC's what so ever. But i have lost over 25 WHP when i put it on the dyno a week ago. Which is is really pissing me off.
If anyone can please shine a light or point me to an idea i can look into. Thanks I just want to take my car to the track and race the damn thing lol
