TB troubleshooting Just finished the Maggie install. Does anyone have the pin-outs (which wires/prongs are what on the TB connector) on a LS2 TB?
Also, does anyone have any troubleshooting procedures for an LS2 TB. I've got the TB code and it could be wiring/splicing but I'm thinking its in the TB itself. I've had both crimped connections and soldered connections. Next step is a combination of both. TB position at idle was 17% at idle with crimps, now its 7% with soldered connections. But I get a TB error rolling into throttle at say 50-80 mph.
My current plans are to take off intake tube, and manually open the TB by hand while datalogging the output on Dashhawk to see if there are any dead spots in the range. But it would be nice to know if there is some way to check the TB & sensor for proper operation.

I know with the maggie installs you should have everything soldered just in case, obviously you checked your connection to the TB itself? If both of those are good then its in the TB itself. What car and year?
EDIT: if this is for a 05/06 GTO it could be a faulty TPS.

What are my options for fixing this if its a faulty TPS? Do I have to buy a whole TB or can I replace just the sensor? Sux if I have to buy a whole new TB because I just paid to have it ported and now this.
Anyone ever opened their TB case? Can the sensor itself be replaced?
