Also they suggested me to took Bardhal engine treatment and somehow I got convinced to do it as my vehicle is around 36K+ Km. After receiving my car it was fine and next day I went to long trip. After 80-90 km run “check engine” light came and car was running fine till that time. But next day it started giving me same old pain. During return I halt at HP pump and filled 10l petrol as I always use IOC extra premium and it was not available. Car problem further increased and it was not going above 80+ for few minutes and I can feel the harshness. After returning pune again I went workshop and they told me that O2 sensor and ECU is probably faulty and replacing them will cost 20K+. I felt they are taking me for granted and not doing justice with job. After talking to works manager and advisor they told me same story and showed me some EMS software which produce all the result. When I asked for codes of ECU which tells the problematic area they said ECU is reset and it cant be given right now. When check engine light appears again they can show me.

Now, car is still giving me starting trouble, its very harsh and it jerks when I try to accelerate it in the morning after cranking it. After a while car goes fine but I can feel it is not so smooth in drive. Also I can hear lots squeaks in-around the car (probably seats or suspension). When I put key and reach to ignition some weired sound comes. The only benefit I have fuel efficiency which is around 12-13 km in city with AC.

Can anyone help me to understand these –

What are the problems related with O2 sensor ?
What are the problems related with ECU?
How much ECU and O2 replacement will cost me outside TASC ?
Can I use Indica vista/Xeta ECU in indigo petrol ?

:- Does anyone in Pune have taken petrol car around 2006 with extended warranty ?

Hi,

I am also facing the same issue what Amitabh has faced....

I have fitted my LPG kit and run alomst 60000 kms without any issues.....Now the dealer is telling me that the issue with ECU could be due to LPG fitment. As such, even now, I am able to run my car with gas mode without any issues...only on petrol, I am seeing the loss of acceleration...Can any one suggest that does this problem need to be addressed only by replacing ECU or any other alternate solution? If this is due to some issues with ECU, does this not reflect even I am running with LPG?

Kindly reply

Regards,

Check your nozzles and injectors. Prolonged unuse of petrol causes such blockages. Cleam them up real good and also clean your fuel pump and pipes. The problem might get solved as basically the issue is with Petrol mode only.

Hi all I'm new to this forum. My understanding of fast idle control is for quicker warm-up on cold starts, not for idle control for increased engine parasitic load i.e AC.
