So I have been having some problems with the LS lately and I brought it in to get checked out. They ran tests on it and came up with these two codes.. -PO717 - Turbine Speed Sensor - No Signal -P1233 - Fuel Pump Driver Module Off Line Does anybody know where these two parts are, so that I could possibly fix the problem myself? The car sputters and bogs down when you step on the gas a little bit. I do not know how to explain it specifically. If I were to hit the gas, the car would stop and jolt back and forth like it was struggling to keep going. Kind of seems like a fuel filter or something. Could it be the infamous coil spring problem? My car is a 2000 V6 with almost 70k on it. Somebody who knows alot more about this, please fill me in. Thanks!
