we are both from the same area i dont know how we would have different emissions i dont think mine is from a different state. as far as a bad apple its my luck that i get one that has all the common issues but im certainly not alone.
and im sure i read in the tsb that they are to be cleaned unless you have done the cleaning then they should be replaced with "mfi"
"General Motors has issued several technical service bulletins that deal with these issues, including TSB 99-06-01-022 that covers procedures for cleaning CPI poppet valve spray nozzles, TSB 00-06-04-003B for cleaning CSFI poppet valve spray nozzles, TSB 56-63-06 and TSB 66-63-09 that cover diagnosing hard-starting/no-start problems with the CPI system, and Special Policy 99034A that extends the factory warranty on California-only CPI systems (RPO L35 VIN Code W) to 10 years or 100,000 miles. The latter blames CPI problems on the use of California’* reformulated gasoline, and covers both repairs and cleaning.
GM also issued a recall (99066F) on 1996 to 2003 CSFI systems, and extended the warranty to 10 years or 200,000 miles (whichever comes first) to cover problems with the poppet spray nozzles. The recall covers free injector cleaning and/or replacement as needed to correct driveability or emissions problems."
