Alright I can't quite explain this enough to search for it.
Basically I am getting two codes on my DSM.
1. Knock sensor circuit malfunction
2. TPS malfunction
So what is weird is that my SAFC will read Throttle % perfectly but I still get this code. I have tried adjusting it numerous times to no change. I tried doing it by the book and still get the code.
But my question is this:
I notice when in D and accelerating at low throttle (from -1 to -15) my car will shift, then feel like it slipped into neutral and shift again.. but remain in the gear it shifted into. It does this twice up to 25mph and almost feels like a slip but I have no other issues besides a few "clunks" when slowed and turning here and there. Also from R to D, sometimes clunks if I don't wait a certain amount of time.
HOWEVER, when at 0 or at 5 psi I feel like this problem dissapears. Seems strange to me but I was thinking this could be TPS related since it is one of the inputs for the TCU.
The car will not do this if started cold and driven. In fact it barely wants to move.. but it does not do this "slip".
If manually shifting, shifts fine from 1-2, 2-3 with OD off shifts fine, but light throttle sometimes raises the RPMS before catching, and shifting with OD on results in RPMS increasing nearly 300-500 before hitting third and then shifting into OD.
And finally all warmed up and WOT when shifting into 3rd it seems like my tranny just hits full neutral so I let off, never have gone past 80 yet.
Thoughts? Ideas? Experiences? Cool stories?
