Thanks Jarpickle & Samsag12, I too hope it's a simple issue.
I have given the car to the Tinker person today. He quoted 800/- for the front wheel well, below rear seat & A pillar work. I Paid him 1000/- & asked to replace the front & rear windhsield gaskets too.
I will check the oil thing as soon as I get back the car. Mostly tomorrow evening I will be getting the car back.
Today it was weird experience, driving car without headlamps, grill, bumper, seats, floor etc. I was grabbing quite a lot of eye balls. My formal dress & the car just dint gel well
The car continued to jerk heavily while driving, luckily the mechanic in that garage fixed the jerking issue.
I had connected the ignition coil in the opposite way (those 2 tiny wires) & that is what caused the jerking. He also reduced the idling (FIRST TIME I BOTHERED TO SEE WHICH SCREW HANDLES IDLING!)
Some strange things happened today when I was driving towards the garage, the fuel indicator showed half tank! where as I had hardly put 150rs petrol only, plus the radiator fan started working. The fan might have stopped yesterday because of lose wiring/switch.
Hope the rains wont enter my car now on. Feeling very lonely now, without the car. Will visit the Tinker this evening to see progress.
