Well basically the car was running fine up until about two months ago, I haven't been driving it since it has been in and out of my mechanics who hasn't done anything lol, he thinks its my tune.
The air/fuels went crazy rich, in the 10:1's. I tried changing the o2 sensor, adjusted tps sensor, checked for vacuum leaks, replaced fuel pressure regulator and made sure return line was unclogged, changed engine coolant temp sensor. I know the gauge is working correctly. I just installed an adjustable fuel pressure regulator the other day and by turning the fuel pressure very low (25psi), I was able to get the car running at half decent air/fuels. Now idling around 12:1 and driving in the 13 and 14:s range. Just don't feel comfortable driving it like this in case i step on the pedal too hard I don't want it to lean out because of the low fuel pressure. My tuner hasn't been responding so I'm pretty much just trying to find someone to do it for me.
