weird pulsation

My car is giving a weird pulsation and everytime it does it my check engine light pops on, does anyone knows what is it?

Rather than guessing, you need to blink the check code.

Your profile says it's an S5.
Code 12 = Long range TPS. That signal is used to run the metering oil pump.

I have had good luck with spray contact cleaner.
Spray it in between the plunger & sleeve of both TPS's.

I get it from the electrical Dept at Home Depot.
