Went to a mechanic in G7 Islamabad. With a light leakage in the engine and tuning works.
The mechanic opened the engine cover, glued the gasket, changed the spark plugs (which every mechanic does each time i go for tuning, i think they have no idea how spark plugs are diagnosed) and did some tuning.
After a day, car engine checklight showed, and the car didint go above 3rd gear (vitz 99 model). Also leakage didnt stop
Went to the mechanic again. He changed 2-3 sensors in the engine. Fixed the gear and suggested leakage is in the head gasket.
A day later. Started the car and it was missing the race so much.
Summary: I took a running car to the mechanic and came home with a faulty gear, faulty plugs and jerks and missing car.
What am i doing wrong here?
