E-303 drama after install
 

I just purchased a 90 gt w/ 150k and a fresh rebuilt w/ aE-303. The issue is when slowing down between 3rd to 2nd shift the car dies I have to pat the gas to keep it running and when idling around in 1st or 2nd the car jerks back and forth.
1.Is this normal for a basic stock motor with a mild cam?
2.Do I need to flash thecomputer after the install?
3.Is there an adjutment to the mass air (efi)that needs to be done?
4. Is surging and stalling due to some overlooked issue?

1. No
2. Yes
3. Not usually
4. Whoever rebuilt the engine could have forgot to connect a certain vacuum line. Check everything over.

OK If I had to flash it i was going to wait until i intalled the 3G and electric fan. What electric fan would say is best suited for a mild built 306?
