Help on op-amp (?) circuit

I've used the LM324 before, and its pretty common.  The LM324 is also
"reasonably" stable.  I'm not sure if you have access to a Radio Shack
in Sweden, however that particular chain store has books that can help
you out.

basically, you want to run the input of the TPS sensor into the op-amp
on the + input, and connect the - input to a variable resistor taht's
connected to ground and Vcc (supply voltage on your circuit), which
you would use to adjust the cut-in/cut-out threshold.

If you can't find the book, let me know, I might have a simple circuit
diagram that would give you the basics, using the LM324, and you can
go from there.  I have the book actually sitting on my dressor at the
moment, so its not buried deep, deep in the dungeon (basement)
