Hello gang, Well, I am at wits end and more or less at the end of my mechanical ability. I performed a full tune up including new cap/rotor, wires, spark plugs, new cat, new O2 sensor. My car runs great, good acceleration, pretty good idle (hunts a little bit 100 rpm or so) STILL FAILED SMOG!! I am going to take the car the Garden Grove and have the guys do their thing again. They are really nice and understanding about this whole thing I must say. Any more ideas out there? The smog tech said that he thought it could be a small timing problem or that the car was not totally warmed up. I only failed the NOx portion again, barely. Ill post the results later tonight. I thought NOX was from HIGH ignition temps, not from a cold engine. BTW, none of these smog people have even seen a Delorean before; they look at it like it's a space ship or something. Could they be doing the test wrong??
