Hey folks, Having performance problems on my 93 C/V w/120K mi. Feels like a 'miss', Maybe.. Checked MAF, clean as a whistle. Replaced plugs, no help. With engine at oper. temp., ran KOEO(twice) and got code 32 first time, code 33 second time. Code 32: EGR Valve Position(EVP) sensor or Pressure Feedback EGR (PFE) sensor - signal voltage is below closed limit or has gone beyond set limits. OR, Problems with EGR valve controlling. Code 33: EGR Valve Position(EVP) sensor or Pressure Feedback EGR(PFE) sensor indicates EGR valve is not opening. OR, EGR Valve Position(EVP) sensor or Pressure Feedback EGR(PFE) sensor indicatres EGR valve not sealed(closed) properly. Last year, a Ford mechanic friend helped me clean out the carboned up EGR passage way, and EGR system was working properly. Have any of you had this similar problem ? Is it likely the EGR or the Sensor(s)? I hate to just go shot-gunning by replacing parts. Thanks for your help, John
