Well last time I filled up I got 132 mi for the tank, what the heck is going on. The car is running really rich and always has been, what can I check out to make sure is going alright. Fuel pressure is set at 42 at idle and the o2's were just changed in june. What else can I check out?

 

plugs, wires, and THE TUNE! Get that thing on the dyno or use lt1 edit with a wide band O2 sensor and do some part throttle tuning.
