The other day when i start my car it had a jumping idle. I figured it was the iacv but there was no cel. When i checked for codes i got 14, 21, 22. My questions are is why doesn't it turn the cel light on to let you know something went wrong with the engine and also when the iacv goes out does it effect the vtec solenoid?
