TB Shaft Seals and low TPS readings...

I did the TB shaft seals a bit ago and have been logging TPS through Evoscan and at idle its 14.5 which is a little high but still within reason, but Im only seeing 32.5 at WOT. Did I install something wrong? Thanks

you can loosen up the screws on the tps and adjust while logging evoscan i belive it should be around 11-13 tps at idle evoscan wont show 0 but as long as your 100 at WOT youll be fine

I take it you didn't read a how to. In the one posted on here, they tell you to mark or scribe a line on the tps sensor/tb for reference before you even take it apart.

yup i think its a 7mm socket on the tps bolts just loosen up a little and you can pivit the tps left and right log with evoscan with car in on position but not started to see changes

I did read the how to, its the only reason I was confident enough to do it. I used a "not-so" permanent marker and between that and my greasy mits the lines were a little hard to see. BLK EVIL my sockets wouldnt go on it, Ima try to find one with thinner walls I suppose
