my engine is an S5 TII Running as an S4 TII with s4 Electronics BUT an FD upper and FD TPS.
now,My Problem is the Car will Run Just FINE with the TPS off the Throttle body(not screwed on) BUT If I attach the TPS to the TB it will buck and chuck,fart,snort etc!
I heard about a PILL that is in a Hose going to the Map sensor?
would that create a Problem If I did not have it on my Setup?

 

it would not relate to this.

 

Besides the setup Sir Cygnus,I would like to know what this Pill does,and what it is for.Thanks man.

 

The pill evens out the signal. In my case, without the pill, the rapid flow to the pressure sensor caused a rapid spike and as the electronics couldn't adapt that quickly the engine actually detonated as it read over the 12lbs max the unit is designed to accomodate, but with the pill, a more even flow was recognized and no problems.

Scroll down to "Vacuum Hose Orifice" it's $3.53+ shipping.

 

you have a s5 motor, s4 stock computer and are trying to run its throttle position sensing off a s6 tps ? , correct or did i read it wrong .

 

Good catch.... The fact that the TPS runs fine unmounted and bad when mounted seems like a faulty wiring issue to me. I wasn't aware the S5/S6 TPS can be used with S4 ECU's since the s5/s6 tps has two plungers....

Restrictor pill has nothing to do with it, but if you need one go to advance auto and look in the vacuum line section for a line restrictor. They usually have them on hand.
