This car is starting to give me headaches and yet I still throw money onto it. Recently, after I installed my SAFC 2, cars been running kind of like chengsta in his thread "
running rich or not enough fuel?" but not as bad. There's another problem with the car that I want to fix before all others for now is my gas mileage. It's been going down ever since I put in the safc 2, but the safc 2 is zeroed out so what's going on? I checked my spark plugs and they are only 1 month old and has black deposits on it so I guess I'm running too rich? The car is blowing out black smoke like crazy too!
I was reading around about what could be causing is it seems like mine is close to a bad front o2 sensor but I want to double check with you guys. Can the safc 2 read the volts on the o2 sensor? If it can, here's what mine read:
In-1: 0.020 v, In-2: .0965 v, thrt: 0.745 v, knk: 0.740 v
I also have the 2g data logger but I'm clueless as to how to read it. I currently can only use the ob2 guage program and for the o2 sensor, it reads some weird number cause it doesn't look like it's reading the voltage.
Please help me figure this out as I don't like driving 10 mpg or less. I want my 25 to 30 mpg back. Some dynotuning is in the future of course but first I want to fix this damn gas problem.
The car is a 2g gst, e3 16g, Greddy 24r fmic, afpr set at 43 psi, NGK BPR7ES spark plugs and wires, K&N air filter, gm maft blow thru, stock injectors and fuel pump, full 3" no cat. exhaust, and currently use 2g datalogger and the safc 2.
