Default Passed smog with flying colors.. anyone have problems?

Just took my 98 for it's (now biennial in CA) smog check. 90K miles. All stock.
Passed by a LONG margin.. I mean, really long (see test result below)

I recently had the intake manifold off (to replace the oil pressure sender), and cleaned up some oil and crud that had built up.
Also cleaned up the throttle body. Also had the fuel injectors cleaned (ultrasonic).

The car runs noticeably better (smoother idle, better throttle response) since then.

Looks like the LS-1 runs very clean into it's old age. Anyone have any problems with emissions?

Thanks for posting your numbers, they look great.
Here in lies the fallacy that the modern fuel injected motor is going to kill us all. Once warm and the cats fire off, a modern fuel injected car that is in good running order is EXTREMELY low in emissions. I am sick and tired of listening to Eco-****'s telling us that the world will end because of the cars we drive...bullshit. One small forest fire or volcano eruption has much more detriment to the air quality than anything a million cars can do. Before fuel injection and computer controls, carbs did put out much more emissions but with today's technology cars are just so good and clean running.

Most emissions are produced in the first few minutes until the cats fire off.....after that, it is amazing how clean our modern cars actually burn. This is why large displacement naturally aspirated motors (like the Viper V10) are going way to make those cars burn clean until they warm up. The bigger the motor, the more emissions it puts out until the car warms up. There is no way to pass the EPA emissions cycle the includes cold start readings. Hello V6's or small V8's with forced induction.

Glad you passed your test, your car is obviously still in good and healthy running condition.

Good luck committing suicide with your car in the the time you produced enough carbon monoxide you would have probably gotten hungry and thirsty for a drink and given up the process. Think about it, your clean burning Vette actually saved your life, lol.

62k on my Z06 and it passed earlier this year with similar results to yours. Nothing to worry about here!
