Hey everyone, About three weeks ago my truck would shutter at an idle I tried replacing the fuel filter, adding Lucas to the tank etc. Had the same problem so I gave up and took to the dealer. When I got there I put it back to it's stock setting on the programmer it still ran like crap. They had it all day and told me that it needed new injectors so I said ok. They had it for a week. I got it back drove it home and tuned it up it ran fine for about 500 miles and started to run like crap again. After I got mad at the world I calmed down. I called the dealer and got the usual crap bring it in and will look at it. All I could think about was another week without my truck so I started asking around about this problem. I got the same answer from quite a few people deprogram it. I put it back to stock drove it down the road and back put it in park no shutter and it hasn't come back. So what I'm getting at is I guess I did not need injectors but so be it. But now I have the worst turbo lag and my speedometer is off and my transmission won't shift right. How come everybody else can run a programmer with no problem. Is it a Hypertec problem or just me. Any suggestions would be greatly appreciated.
