I haven't driven it much in the last 2 years and it starts running on 7 cyc then after it warms up it will start running on all 8cyc but it has the original injectors and I have new Bosch 3's but should I try Bernies in the gas tank or in the fuel rail Schrader valve first. The tank is full with new gas I replaced the idle air control valve witch was all carboned up and cleaned the throttle body and Mass air flow sensor
visually confirm you get good spark on all 8 cylinders.

I would definitely start by putting Bernie's stuff in the gas tank (I have never heard of putting Bernie's stuff right in the schrader valve at the fuel rail). If that doesn't work then check your injectors to see if they need replacing
