you are lucky, i have spend 18,000 last time not more than 4 months ago and now also spent 23,000,
engine is also getting hotter and stops working on first gear and pick is not good, and when ever i lower gear from 4 to 3 or 3 to 2, i heard jerk sound, as we are driving in wrong gear.
mechanic is unable to tune it on petrol he says that one of the sensor is not working properly and providing more fuel than normal. which sensor is involved here?
what MAP sensor do?
