Borjawil Posted October 2, 2020 Report Share Posted October 2, 2020 2009 sxt. Recently swapped in a 3.5l as my 3.5l had issues. Had a #1 misfire and o2 code. Replaced o2 sensor, plug, injector, and coil. Recently checked and only had the misfire for #1 and random misfires code. This info is just in case it's related, though unlikely. So at this point I was using the intake from original engine. Other one was dirty. Thought a crack or other issue causing misfire. So I swapped donor engine intake on and replaced the gasket. Got a code for bank 1 tuning valve. P06xx code. Swapped tuning valve in rear of intake with the one on the intake I took off. Now I have the p1005 code. No misfire code as of yet. Ideas?

Borjawil Posted October 2, 2020 Author Report Share Posted October 2, 2020 (edited) Misfire code came back so that's neat. But looking around seems the intake itself could be bad or I saw that a short in a wire above the drivers sun visor can cause the code some how. Thoughts? In the next couple days I'll swap the actuator back to the original intake and swap that on with the new gasket and see if it's still and issue.
