Car idle is a tiny bit to low. When the car is ticking over it vibrates Alot more than it should but if I rev it just (slightly) the vibration comes out of it. How do I adjust the Reves I looked around the throttle body and don't seem to see anything. Car is idleing just under 800rpm but if I keep the Reves at 800rpm exactly using the accelerator pedal the vibration goes. Tanks for reading

It's non adjustable, try cleaning throttle plate on both sides and iac hole with choke cleaner then if still doing it check for a vacuum leak.

Scan for codes and check fuel pressure with a gauge then. We don't have a 1.4 in those cars here in U.S. So you may have to go to a shop
