Need help with Single Shot Injectors- SOLVED
Six weeks ago I installed Full Force Reman Single Shot 160cc. I went with TW tunes which I am running on a Hydra. My problem are multi-faceted but I will try to describe them the best I can. Also I am on my 1st set of revised tunes from TW and they still aren't quite right.
1) As soon as I put the truck in drive the rpms jump up to 900-950 and won't come back down until it's back in park for a couple of minutes.
2) Throttle is really touchy. When the torque converter is locked if I let off/on the throttle it results in a hard jerk through the entire drivetrain. It feels a lot like differential lash but I know it's not as I did not have this issue with the stock injectors. Also because the throttle is so touchy cruise control is almost impossible cause the truck starts bucking trying to maintain light throttle.
3) When coasting between 15-30mph the idle hangs at 1,000rpms and sounds like the injectors are cutting in/out constantly. Its really, really annoying.
4) The SES light flashes randomly all the time and I am getting a P1316 code. I never had this code prior to the single shot injectors. And when I installed them I put in all new OEM harnesses/gaskets in. I have ohm tested and buzz tested the injectors with no faults detected. This one has me absolutely stumped.
I would appreciate any help, at this point I am really regretting putting in single shots as my truck runs worse now that it did with worn out AD's.
