Okay..code 511 is pcm rom circuit malfunction(I believe) which I assume is coming from the sct chip I recently got burned. Code 189 fuel system lean at partial throttle? Why would this be when I just got my car tuned? These two came up under the obd1 scanners "fast codes" and then on the slow codes it came up with 511 again and also 111. 111 means system pass code so does that mean I really have no problem? Should I be worried about any of this? My check engine light comes on periodically and is annoying. What do you guys think?
--I also believe I have a slight exhaust leak coming from the header or where the headers meet the h-pipe.
