ok guys I need some help.
I have been having this crazy knock issue. its there some times and some time its gone. I seem like every time we get the fuel trims right, the next time I drive the car, the fuel trims are out of whack.
last night, I finished installing my meth, using 100% so I took it for a ride, the first log, there is zero knock, all the pulls I did and nothing. I stopped to turn the start point up alittle, turn the car back on and right away I had knock, at idle, and then again, all the pulls I did had knock.. Is this possible that maybe the fuel filiter needs to be replaced? is this fake knock, I cant tell.
thanks in advance
