Thanks for jumping on board David.
I bought a Bosch unit not the universal. I have even swapped it out withe old one with the same results.
I am in the process of re checking the airflow sensor pot. Is there a set of numbers (ohms) that I should be able to read with the unit out of the airflow meter or must it be installed in the housing.
I have only 2 things left to change ecu or airflow sensor pot. (no longer available I'm told)
