348 start problem

90 348...when cold, it starts great, then starts to stall. Giving it gas keeps it running. When I put it in reverse to back out of the garage, it starts to stall again until I give it more gas. After a min ute its just fine. Fuel filters? Adjustment of air fuel mix? Techron? Wet plug? All of the above? Any thoughts appreciated

 

First, do the basics. Disconnect the battery for 15 seconds when the car is cold. Then start the car while making sure that the throttle pedal isn't touched until the fans come on to cool off a hot engine.

That will reset the A/F ecu's which solves many, many problems.

If that doesn't work, then start here with the air bypass screws: http://webpages.charter.net/aircover/348/1994Ferrari348Spider.html#EngineStallsOverheats
