Answer 1

Sounds like a (TPS) sensor, you will need to scan the vehicles computer and get the readings off the sensor.........

Answer 2

spark plugs? check them. that would be my next move.

good luck

Answer 3

You change this parts to fix the problem or it started after?

You have a vaccum leak.
