1999 Volkswagen Beetle GLS 4 Cyl 2.00L

Preventive Maintenance

Changed various parts and still trying to find reason why it still has a idle problem...

after replacing battery, coil , plug wires and Fuel pressure regulator, car no longer had engine warning light on, but now after checking for other problems, took off the Mass air flow sensor and the engine ran great for just a minute without any idle problems..Do I need to replace this part? is there a test to prove that this is a problem?
