Need second opinion, Tech at ind. shop believes that
4 blinks is Airflow Sensor. He says a very pricy part. ($400) Wouldn't know for sure until part is installed.
Also said 1 blink is end of codes. Due to my budget I may
have to get at auto recycler. I was wondering if anyone
has replaced these things and what is involved. Do you
need any special tools????? etc.

Also, EHA is leaking fuel. Will o-rings fix this????
I an wondering if these parts fail very often. (EHA)

Any ideas?????
