You can try some snap on chokes Mix 31 over the injector wires if there are any you can get to. Also make sure hood is bonded at 2 edges (back edges obviously), make sure the exhaust pipe is bonded at least 3 locations along its length. You can use large SS hose clamps for the exhaust pipe end, and use stainless screws and star washers all coated in No-Ox-Id on the chassis end. Keep all bonding straps as short as possible.

I don't want to say im glad im not the only one that has engine sounds coming into my brand new ft891 but i thought about getting a rfi kit from palomar engineering  for the radio.  I have a 2007 honda accord so I have engine, injector, modules from cars computer i guess , all going into my ft891. the only time i can hear decent is with the ignition off.

Welcome to HF mobile!
Have you contacted Ford about this?  A LOT of Ford products are used by Govt with radios and the vehicles need filtering. They may have a kit.
