TPS mischief and mayhem
OK, so I am still working on my 94 B13 SR20DE. Been having issues and situations with this thing for a minute. ECU through two fault codes of a bad knock sensor and bad O2 sensor so got those changed out.
I am having trouble with timing the vehicle because I can't get my TPS dialed in right as seen in the picture. With the throttle wide open I get a NEGATIVE voltage reading. As I open the throttle the voltage reading does down and that's not supposed to happen. The TPS was purchased by a member of this forum and was told that it was a working part.
Has anyone run into this problem before? I ask because perhaps there are some little things out there that I don't know about pertaining to the ECU or timing. I have researched on the forum and have seen other guys having similar issues....input appreciated.
