I was noticing that my TPS was only going to 20% closed via my Torque app on my 1999 Ford Escort Wagon
That got me started in on wanting to calibrate it. I found that the TPS was sending 1.5V to the ECU so I did the waller out the screw hole mod and got it set at .96 .

I had to remove my throttle body to get to it to get the TPS screws loose and found that the pcv gunk had totally painted the butterfly with a thick coat of lacquered oil.

Just think about what that mess does to the top shoulders of your intake valves.

That right there was enough to decide to immediately install a catch can.

I had one on a 2003 Saturn that caught a lot of crap.

Anywho. after setting the TPS to read .96 on closed throttle my idle smoothed out to kitten purring levels and my throttle response and hill climbing is like a whole different car WOW!

It must have been running as rich as the ecu could possibly let it and I bet the shift points were off too.
I am looking for some huge mpg gains now.
