Thanks for the response! Yes I had driven 40 miles at highway speed; car waited about 8 or 10 minutes before he started testing. Aftermarket cat with only about 3K miles on it. Premium fuel about half tank. The car is stock, not chipped. This was the second time it just barely failed - the first time I thought perhaps I just had not driven the car enough after re-connecting the battery (for the computer to get the fuel trim right), but then I also replaced the fuel pump, filter and pressure regulator prior to this re-test. Afterwards talked with an indie shop guy who suggested NGK plugs and new coil boots - I had not considered chip; was not sure that was OK in Calif.Originally Posted by califblue
was your car warmed up when you went to the test? ...hot enough the catalytic converter was ticking and I always use minimal fuel in the tank too.
Is you car chipped?
I have a Mark D chip and mine runs so clean the test guy says they are going to come and test his machine...LOL
