Wrote a previous thread about how my 96 ss would choke from idle with a dose of gas. I unhooked the mass airflow sensor and my problem pretty much went away for the exception that at least on cold starts I had to hold the throttle to the floor to get it to start. Seemed to me a new sensor was the fix since if I had it unhooked there was no more choke/stumble. New one didn't work. Any ideas at all would be helpful. Also when I hooked up the new sensor I could not get the car to start. Thanks JZ.
