I had a problem with the car over fueling on boost so replaced the map sensor and it has cured the problem but since changing it my monitor shows my TPS % jumping all over the place. At idel it reads o% but if you just touch the throttle it jumps to about 80% and then jumps all over the place.

Car drives fine with no holding back or missing so is it a faulty TPS or just the monitor not picking up the reading correctly.
Just seems strange it started after replacing the map sensor.

Sounds like a dirty signal from the tps but not sure if only the sensor would be struggling with it or the ecu too. As you say the car is running fine it does sound odd.

When my tps was faulty the car was backfiring while slowing down and jerky throttle from engine
