Q: Skoda/VW Intermittent power loss and RPM shooting high - If clutch then how its coming up Just after Car Servicing

If the symptoms you describe started literally the instant you drove away from the repair facility (as opposed to commencing even a day later) then the likelihood is an electrical connector, or vacuum line, was disturbed during the service or some other "mistake" was made, yet to be determined. If there was a lag between the service and the onset though, then the fault you are now having is probably just a coincidence (of course, even the first scenario could be a coincidence but it is not "likely"). To resolve the first scenario, the work performed will have to be re-visited to find any faults. In the second scenario, a diagnostic would have to be performed to find the cause. A recommended service would be an engine loss of power diagnostic. To give you an initial idea, although there are many possibilities, a partial list of causes of loss of power would include oxygen sensors, fuel pump and/or filter, vacuum leaks, ignition system malfunctions, bad valve timing if the timing belt or chain is worn or skipped, blocked exhaust (e.g., catalytic converter fails or becomes clogged), airflow sensor, throttle position sensor, and so forth. Whatever the cause, if you request the engine loss of power diagnostic, the certified mechanic will get this resolved.
