500 efi blue racing running bad!!!
hey guys I have a 27’ Fountain with a 500 efi with very rough idle & sometimes acts like she wants to die, have to bump throttle a little & she idles fine, hesitates, coming out the hole & once I get her on plane I try & give her more throttle, she hesitates, sputters, just not accelerating like she should!
PLEASE HELP!!! I’ve had computer scanned no codes, changed IAC valve, changed plugs, fuel filter!

THE FAMOUS 500 EFI FUEL INJECTORS
MULTECS do not have to say anymore.
And fuel pressure
Your source for 2018 injectors instead of 1989 MULTECS
When I went to Bosch in person THEY COULD NOT BELIEVE THAT ANYONE is still using them in current times. Just saying
