Review on YZHIDIANF Fuel Injector Fits 16600 EN200 by Sam Carter

I don't normally write reviews but given the pain of installing new injectors I thought it was important to warn others not to buy these things. I am very disappointed in this. So I should have known better when I bought something less than 4 stars which was 1/6 the price of the top brands but it's an old car with high mileage and I figured they might have a few years hold. First the packaging was suspicious and then I should have known that they probably wouldn't be high quality parts. They were in plastic bags which were dirty/oily then just tossed in the box. However the bags were not sealed so 3 of the 4 injectors came out of the bags during shipping causing them to hit each other. Since my car was already disassembled, I decided to install it. Now the car runs really worse than with the old injectors. I checked all the electrical connections and they look fine. Doesn't work and knocks. I'm getting code P-0300 which could indicate a problem with the fuel injector and since I haven't changed any other parts it's pretty obvious this isn't good. I'm sending them back and ordering a set of Hitachi injectors.
