Well my buddy has a 87 non turbo. And at around 4000rpms his fuel cuts off. That is if he gets on it. I was just wondering what could it be. Mabe his secondar injectors are not grounded or what? Any feed backs will help. Thanks

 

list of modifications would help..

 

there is no fuel cut in an N/A... his secondary injectors probably are not opening. try regrounding them at the ecu.

 

The plug may not be on the injector all the way, or could always be a vac leak.
