Experiencing it from the moment my car serviced at a 3rd party SS. And its still there even after 400 miles.Can it be a clogged TB or a vacuum leak ? I own a Skoda Rapid (MT) petrol, 5yr, 40000 kms done. As a part of general service, the engine oil, air filter, fuel filter and transmission fluid was changed. Before the service, my car acceleration and pickup everything was perfect and I didn't feel any lag. Just after the service, I felt that my car loses power after gear shift for a moment, in second gear, I have to accelerate a little on speed breakers unlike before, and the rpm is going higher so soon but with partial power being convered into wheels as a result I need to change gear sooner. Earlier I used to go 80+ or even 100kmph on 4th gear, but now since rpm touch redline, I have to shift up sooner.Unlikely to be clutch, as I'm experiencing it just after the service, and till date. But never before service. Please list out the possibilities.
If I understand your narrative correctly, the malfunction occurred exactly coincident to the "service". That raises the possibility of mistakes such as incorrect correct gear (wrong viscosity) or inadequate amount or perhaps components were mistakenly removed and not re-connected (e.g., vacuum lines, sensors). You might re-visit the shop and let them know the problem started the instant you drove off the lot which obviously is quite a coincidence if they had no role in causing the malfunction. Their response to that inquiry will provide a clue: if they are dismissive of your complaint, and reluctant to assist you, that alone would tell me they may have very well caused the problem. Typically, loss of power on acceleration can be due to plugged fuel injectors, faulty oxygen sensors, fuel pump and/or filter, vacuum leaks including that caused by a faulty EGR system, 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), a faulty airflow sensor or throttle position sensor, and so forth. To pinpoint the exact cause will require an engine loss of power diagnostic. If you request that diagnostic, the certified mechanic will get this resolved for you.
