History
This is my first vehicle I have ever owned and bought myself, and got it on a lien sale for a great price. However the CEL was on with a code 52, but no big deal the truck ran fine when I test drove it. Over the last year my truck would run worse and worse with a huge loss of power, cant drive the freeway's, and cant go faster than 30 mph. The CEL light would not come on till I hit 1500 - 2000 rpm though. Fuel, someday's I would have to fill up twice a day it seemed like I was just working to pay for gas, horriable gas mileage. Finally I broke down and replaced the knock sensor along with the pigtail. Once It was back together I fired it up and CEL came on still. I bought the knock sensor off of Ebay as well as the pigtail. Now I pulled the plug into my ECU (16 pin plug) and where there should be a black wire for the knock sensor there is nothing at all.
