Ls swap issue, dtc P1689 Ive got a sierra -94 with ls1 swap and 4l60e trans.
411pcm from -03 vette and The engine is from an -97 vette with dbw.
i have dtc p1689 and The car runs fine for about 3-5sec and then it starts to misfire and run bad.
i have tried to remove vats again, steering column, disable dtc in hptuners but nothing helps.
anyone have any ideas how to do next?
im stuck and dont know what to do next..

That's a traction control code, likely because you don't have the EBTCM, but shouldn't affect the way it runs. I suspect you have another problem that is not related to your current DTC. Fuel pressure good? Wiring all good? Grounds clean and tight? There's a lot of things that could be going on. Is that the only code you are getting?
