I wanted to know what you guys think about my 7a it feels low on power until you hit about 4000rpm and the power kicks back in it smells like it is too rich but I have tried adjusting the air fuel rate but it’s not done much I have replaced knock sensors and the lambda sensor both made a small difference I cannot see any air leaks but the previous owner has removed a few bits one of which is the pipe that goes from the air intake to the crack I believe it has been blocked off in the intake side but I don’t know if that’s the problem or not?

still on the old hitachi injectors?
hey might be not sealing fully and dripping to much fuel into the engine. dripping injectors also give a shakking effect on idle because it will run to rich.
Had this in my old 7a, on changing the injectors to bosch units idle was better, more power in low range.1967 fiat 500 future project

Whatever you have done adjusting air fuel ratio won't make any difference to the mixture running as that is controlled by the lambda probe feeding back to the ecu, the map in the ecu controls mixture. Not adjustable other than at idle.
Do a Google search or search this forum to see how to check fault codes, your car may tell you what is up.
