Emission Test Results
2500 RPM
HC (ppm) Limit 200 - Reading 208, CO% Limit 1.00 - Reading 7.17
Idle
HC (ppm) Limit 200 - Reading 508, CO% Limit 1.00 - Reading 7.56
Has anyone seen this magnitude of failure before and if so what was the cause?
According to my OBD-1 program the car is running rich all the time.
I am thinking that this radical failure is likely due to a failure of the Air Injection Valve Solenoids. I will be looking at the engine cold condition
and the warm condition to see if the Air Pump output is being switched correctly. I am thinking that the exhaust is being fed continuously
with air causing the O2 sensor to think the engine is running on the lean side forcing the ECM to add more fuel.
Anyone have and thoughts or experience that may help?
Thanks WTS
