Damn code 51/31

You only need to replace the housing if it's been damaged or in some other undesirable way altered. Code 31 is purely electrical. Do you happen to have any aftermarket fuel controllers installed? If so you may need to power them up before the ECU gets power... if not, pickup your TSRM and diagnose per the info in the book.

Hmm.. So if I adjust the tps? Do I need to adjust the timing as well? I just have a rough idle (500/600 rpm), it will actually shut off if I rev up real quick and let off the gas..

I am pretty sure I got the tps correct..

What am I missing here..

Hey do I need to do my timing if I put on a different TPS?

No, just calibrate the TPS as in that link I posted.
