Actually, most of the mefi programs do a "partial enrich".
Usually 100% throttle = 0% BPW modifier. If you are having closed throttle start problems, clean the throttle body blade area and don't forget to clean the IAC and it's passage. :) I would check the IAC motor it sounds like you are not getting enough air to start. When you get it started and it is warmed up put a scan tool on and check the iac counts. Should between 5-25 |

Could be any of the suggested causes or leaking injector(s). Any gas smell when she starts? |
I was confident someone on this board would step up and help me out...as usual. I want to thank Dean Gellner of Gellner Engineering..AKA...MRHORSEPOWER1 for helping me. He gave me a great deal on new injectors and provided good customer service. That's what it's all about.
Thanks Dean- |
Awesome to hear!:D

The injectors are the same thing that G.M. sales. After all thay are GM parts..Bet ya did'nt know that...:cool-smiley-011:

I needed the older MEFI 1 injectors. I'm not sure if they are exactly the same as the GM injectors??? No one could really cross match the GM and Mercruiser part numbers and give me a FIRM answer....and I didn't want to take a chance. So I bought the mercruise injectors. I know I paid more but Dean gave me a good price and I have piece of mind that the flow rate is exactly the same.
