Pablo, or whomever..
What would some of the symtoms of being TOO rich be??

I installed the edelbrock perf ( carb ) non egr manifold w/ holley adapter plate. Unfortunately, its falling a bit flat about 4200 rpm. bogging down, some missing. Yes the crossover is block off. I was thinking it was too lean, so swapped in some 350 injectors, am running 13.5 psi on pressure, and I can adjust it. Gott any ideas??? or suggestions?

Thanks guys.

 

thats way rich

 

OK.. guess it's back to the stock injectors, I set the pressure at 12 psi, but the 350 injectors are a LOT larger. Tried to use the O2 sensor w/ a multi meter set on the 2000 scale was at half throttle when it was reading 845, of course I could be reading or using the meter wrong. It's only been 25 yrs since I picked one up. Do you think it'd be a good idea to switch back to the stock injectors then and leaving the fuel press at 12 psi or just put the stock regulator back. The afpr I put in was from turbo city.

 

Yes, go back to the stock injectors and leave the regulator alone play with the pressure see what runs best
