:sosad: Help with smog inspection please! I bought an 88 Turbo automatic as a bit of a basket case. Paint me stupid! Broken timing belt and a lot of the engine in the hatch. After assembly it runs fine but will not pass California smog inspection. Here are the results:
/CO2 /O2 / HCPPM / CO% / NO PPM
Test / RPM/ Meas/Meas/ Max/ Ave/ Meas/ Max / Ave / Meas / Max/ Meas / Meas/
15mph/1733/ 13.90/0.38 / 106 / 31 / 178 / 0.70 / 0.10 / 1.07 / 762 / 32 /
25mph/ 1708/ 13.69/0.35 / 81 / 20 / 194 / 0.57 / 0.09 / 1.27 / 701 / 64 /
I hope this failure report comes through readable. If it gets scrambled I will try again. As you can see, I failed on both Hydrocarbons and Carbon Monoxide.
I later found out that the car has a history of failing. Failed six consecutive inspections actually. Not sure what the owner thought he was doing.
So far I have replaced the O2 sensor, air filter, spark plugs and realize that I probably need a new Catalytic converter. I hesitate to do this right now because I believe that the car is running very rich. I wiped out the tail pipe and took the car on a 20 mile drive. By the time I got home the tail pipe was again coated with a heavy layer of fluffy soot. Seems to me that if it is running that rich, I am just going to poison the Catalytic if I put a new one in with the car in this condition?
I guess I have two questions. What would cause this thing to run so rich? Or, will a new catalytic fix the problem? I personally doubt it.
Any advice appreciated.
