I had a check engine light and the had to replace the o2 sensor. I also changed my plugs and cleaned the fuel injectors recently. I have driven 1000+ miles highway and local after changing the o2 sensor, But the EVAP and air flow cycles are note complete and I cannot get my inspection done.
Thank you in advance for all your help
I recently replaced the thermostat on my 2003 Jetta 4 cylinder. The engine temperature is normal at 190F. However, I cannot adjust the inside blower temperature. It is always hot. The fan works and the heat can be directed to defrost, vent and floor.
I replaced the catalytic converter about 3 months ago. When I accelerate quickly the malfunction indicator light that is on starts flashing. The car hesitates but once I let up on the accelerator & keep an even speed it stops blinking is just lit up. My manual says a blinking indicator light is an emission issue with my catalytic converter but the 413 code says secondary air pump open circuit.
