hi all! I need advice, I have 2.8 MPFI and recently I took it for the first time to computer diagnostics, it gave an error on detonation, 43 if I'm not mistaken, we looked behind the engine and saw that the wire at the knock sensor had come off, everything was connected, the error did not go away. The computer also writes that I have a rich mixture, and the sparks are white, according to the sparks, the mixture is poor. It started after my injectors died, I live in another country and my new ones cost a lot of money, I put injectors with 3.0 Ford v6, needle-shaped, just after installing them for the first time, a detonation error came out. So the question is, what nozzles does this motor like besides stock and where can I buy them? It’s convenient for me to bring them from China, the same AliExpress, but it’s scary to order, give me advice on what to do? and what to check? Thanks!!
new spark plugs, no vacuum leaks
