High RPM

[Rahimli]

Hello friends. I drive Hyundai Matrix 1.6 2009 (petrol engine / automatic transmission). After changing 4 pieces of belts, timing belt tensioner, timing belt idler, 4 pieces of spark plugs, fuel filter and fuel pump filter (it looks like a white pillow) I see that car works in high RPM, it needs a long time to change transmission steps and I've got high fuel consumption now. Before maintenance, I rarely was seeing my car reaches 2000 RPM or high till 60 km/h. But now usually I need to get more than 2000 RPM for changing transmission steps.
Thank you for your time.

You have done a lot of work.
Do you think some of your work has caused this new condition??

 

[Rahimli]

Yes, because everything was normal till maintenance done and I left service centre.

So you didn't do any of the work yourself?
Then how will you find out what is wrong?

 

[Rahimli]

No, everything is done in the service centre by technicians. Now I need to go to another centre to fix this issue I think.

Sorry about all the problems.
