I wanted to share my latest experience with GTX.
The car started emitting lot of black smoke while running at low rpms and fuel efficiency dropped to 5kmpl in city limits.
I took the car to Gowri Automobiles(venkatesh) and explained him the problem. As the first set, he checked lambda sensor and car started behaving normal (no smoke from exhaust)
However, within another 200km round trip, the problem started again,
Took it to him, he replaced something called fuel return valve and told me it is fine.
It looked alright when I took the delivery but within couple of days the problem cropped up again
I was really loosing my patience but asked him to fix it properly.
This time he checked all the sensors and also cleaned up and refitted the MAP sensor and Throttle body.
To my bad luck, even this could not fix the issue as car started emitting black smoke again within 2 days.
This whole process has taken about 2-3 weeks of time and I did not want to give up considering the knowledge that we all have on FIATs.
This time, he too was frustrated and asked me to leave the car for couple of days with him in the garage as it was challenging him in terms of his technical competency.
This morning I got the call from him saying the car is ready and went to do a test drive.
To my joy, the car is back in immaculate condition.
There is absolutely no black smoke and idling is rock study and at 800rpm. I can hit the 5000rpm within 5-6 seconds in the lower gears easily now. and the pick-up is fantastic.
Thanked him to have fixed my car perfectly.
The total cost of repairs: 3500 INR (Labor + for fuel return valve as what he calls)
I have always had a good experience with him so far. This was an exception in the tenure of 9 years of my car service with him.
He took it as a challenge and brought my car to glory with his experience in FIATs.
I'm happy for one simple thing. He did not ask me to go and get any new parts. He was ready to spend his time to analyse and try to isolate the problem by taking one part at a time and fix it.
However, I had the patience as well as trust in him that he can fix this problem.
If I had taken my car to anywhere else, donno might have got ripped for 10-30K INR depending on the list of parts to be replaced.
Will post my experience after a long drive this weekend. planning to take my love for spin on National Highway
