Revs up and down problems

Problem with my car 
Solved
Volkswagen Jetta 2001 120000 miles
I own a standard Jetta 1.8T 2001 and, after perfectly starting the car and changing from first to second gear, EPC and ASR indicators turn on. I stop the car and it is not stable enough, revolutions go up and down. I then turn off the car, start it again and the same problem appears. Occasionally, after a while of driving and braking, the car stalls. Filters and spark plugs have been checked, injectors cleaned but everything is still the same. Could you please help me? It is really worrying and even dangerous. Thank you.

In case someone has my same problem, this was the solution to my problem: acceleration body cleanse, coils harness replacement and engine relay change (N° 428), which is located behind the MAF sensor, right next to the fire wall. Hope it helps someone.

RE
My 2017 VW Jetta had EPC and engine light on, and I took it to the dealer service in Summit, NJ. After the mechanic performed the diagnostics and found wiring damaged caused by Rodents. The wiring was repaired and rechecked and fault lights were cleared. The cost of the repair came to $564, not including sales tax. $555 (labor), $9.36 (2 connectors). I believe that I was overcharged with Labor cost while replacing $9.36 parts. I don't know what to do. Should I contact VW headquarter?
