Need help. In the last 6 months, at different times, I've replaced the Coils, Injectors and fuel pumps. Now, when I'm in Full Power mode it gets to 3,000 rmp's and goes no where. It gurgils and sputters along. I have checked the vacuum, no leaks. I've checked the fuel pressure 42 steady revs it and it goes to 50. Checked the secondary injectors they read 14.8 across the board. Looked at the secondary through the pellum and they seem to be working although the right side seemed a bite slow on the first try, than got better on 2 & 3 pulls. I'm thinking that it might be the secondary system in general. Could the linkage for secondary be fubard. Would like to narrow it down before I pull the pellum. Oh there are no codes. Any thoughts.
