Worrying about smog test results and very low local MPG (89 Integra)
89 Integra with 150,000 miles on it.
2500 RPM limit avarage yours HC(ppm) 140 20 53 CO(%) 1.00 0.1 0.4 CO2(%) 14.2 O2(%) 1.0 IDLE(800 RPM) limit avarage yours HC(ppm) 120 29 112 <-???!!! CO(%) 1.00 0.1 0.08 CO2(%) 14.4 O2(%) 1.0 The HC result when idle was too close to limit. And the gas consume is very high in local (San Francisco, city). No more than 10 MPG. But on freeway, it's pretty good, about 30 to 40 MPG. So what's wrong with it? PCV or O2 sensor? Thanks!

correct it? Thanks! "SoCalMike" <mikein562athotmail@hotmail.com> wrote in message news:<_hEVa.8894$cF.2386@rwcrnsc53>... > > So what's wrong with it? PCV or O2 sensor? > > sounds like O2, with a possibly bad cat converter.

Re: Worrying about smog test results and very low local MPG (89Integra)
Since it passed the People Republic of California test, I won't worry if
it's my car.  Did you change the air filter before the test?
