In the past 1 month, I have been facing acceleration issues in my TJet. After the 3rd service the issue became more prominent - at times the turbo kick was not felt and engine knocking was also felt. I have spent around 5-6 trips to FASS including almost 4-5 full days at FASS. FASS always suggests "Sir everything is fine, there is no error on examiner; you are unnecessarily concerned". I got spark plugs changed just to be sure that they were not causing any acceleration issue Now today, cranking the car failed. After multiple tries the car started. I switched off the car after idling for a couple of minutes and again tried to crank it. The car started after 2-3 attempts and the EOBD failure light stayed on after ignition and the message "Check Engine" came on MID. The battery was changed just a few months back - so battery should not be an issue Should I drive the car to FASS or call RSA for assistance (car is parked at my residence and I have not driven it since this light came on). I guess I shall have to wait till weekend if I have to take it to FASS - the Jet will rest till then Various international forums seem to suggest that it could be some sensor/ECU/fuel pump/ignition coil/etc. My general experience with service centres in NCR is that they are "plug and play" centres. If the problem does not go away by replacing a component, FASS is generally clueless on what has to be done. As part of 3rd service, all oils were changed. Not sure if while the oil was coming out it fell on some sensor and is causing an issue I shall update the error codes shown on the examiner once I visit FASS and they connect the examiner. Any pointers on the solution or existing threads would be helpful.
