Hi everyone, I recently bought a 2013 Prius three, a beautiful car! But, two days after buying it, I noticed a very loud knocking and rattling noise in the gas engine when it starts in the morning or when I start again during the day that lasts for like 10 seconds. I changed the spark plugs and the ignition coils but that did not solve the problem. Eventually, I thought about the injection, I bought Lucas for gasoline cars (grey bottle) and poured it in the tank, drove on the highway and it worked like magic!! The noise is gone, the car is much quieter, smoother and stronger. before you waste your money and time on changing the spark plugs or coils or even going to any mechanic or the dealer, buy one of these bottles and put it in your tank. It is not harmful at all and can use it any time and with any quantity. Sorry forgot to mention, Lucas costed me $8 a bottle (I used one on a full tank) and the spark plugs and the ignition coils costed me $300. I wish I thought of block injectors before I wasted $300 on new parts that the car did not need.
How many miles on it? Have a read through the EGR info link in my signature. (If you’re viewing on a phone, turn it landscape and you should see sig.)
