I swapped a USDM 2000 SI engine in my 97 EX had it all wired and worked fine for about a week then all at once the knock sensor started throwing a code, vtec stopped engaging and my spedo died. If i step on the gass the needle goes up but if i let off the gas it drops to zero. It used to work. all the fuses are fine and the knock sensor is plugged in. Im not sure why its not working. its also a 2000 so i dont think the vss would be bad and it has never been touched so i dont think it is loose or any thing. is there something maybe wireing wise that would affect all of this? any ideas? the Vss worked fine in the si and i pulled it and put the swap directly in the 97 it has never been messed with. if you guys have any ideas of what could be wrong let me know.
Thanks
