Greetings,

My car sometimes gives a little juck when gears changing and hold lights comes on and flashing on dash board.

My local auto electrician scanned and detects No errors, he also open and checks the ECU, found a little corrosion on two transistors but problems remain same.

My local mechanic still trying to figure out the reason and solution.

Best Regards,
Mark

Hi,

It could be an engine tune up problem check the spark plugs, coils and ignition electrical system. The TPS and Vehicle speed sensor could also give you this condition if not adjusted correctly. I'm attaching a symptoms chart below for your reference. let us know if this information is helpful and what corrected the vehicle.
