OK here's the DL I've replaced the plugs, wires, cap & rotor which cleared up a horrible miss, but still no power, I checked the air filter and checked for kinks in the exaust, both OK. It feels like its being restricted, there was no sign of head gasket problems, I retrieved the codes from the computer but dont have the ones I got in front of me, one was to do with the EGR (326?) and a lean condition on the front o2 sensor (172?) one or two others but none I felt would cause a drivability issue, so before I get deeper into this I thought I would ask around here first if any one has any suggestions or ideas. Even at WOT it just acts like its out of breath, I checked the codes because the check engine light came on briefly duing one of my test drives (BTW its my father in laws car) I just would like maybe a starting point if anyone has an idea.
