I seem to have a miss or a jerk between 2000 and 3000 rpm and sometimes it doesn't start as easy as it used too. I have no cel. I did have a p0125 and I cleaned my 02 sensors and it went away. I gutted my pre-cats 2 years ago and put spacers on my 02 sensors. After the problem began I have replaced the spark plugs and coil packs but still have the same problem. I have a scanner and I am not sure what to look for. I have no codes and no pending codes. I also pulled the map sensor and cleaned it. I would appreciate any suggestions or direction.
