Few weeks back my car went for a tune up, Reason was that whenever i would shift into Vtec above 6000RPM the car would lose power and then get a push again, This was in all gears.
Now that i have my car back and i dont have that problem any more. there is a new problem that i have encountered, My car is not performing the way it used to .. I mean i use to hit 120km at the end of 2nd gear and now its only 100 at the end of 2nd and the car has not the same power as it used to i mean in every gear. I can feel it in 1st thru 3rd gear. It doesnt perform the same.
Now what could be the problem?
I know the car is slower than before.I want it the way it used to be.
please advice.

 

120km at end of 2nd gear?!?!?!?!?! 120km is roughly 76mph (dont know for sure, i'm not driving right now, but i know its somewhere around there). my 2nd gear tops out at only 62mph. 62mph is exactly 100km.

everthign seems normal to me.

my bad actually it used to be somewhere around 105 kms. I know for a fact dat my car is slower than before.
I hav no idea y this has happened.

 

Sounds like before you had problems with either the fuel map sensor or the timing. It is possible that they went "too far the other way with your fuel map" Is this possible guys? Could it have been running too rich before and now they went the other way too far?

 

Is the car stock? If so then the fuel map change is not really possible. There could have been a problem with the MAP sensor and they replace it. It's possible the new one is bad too. Try tapping on it with the handle of a screwdriver.

What did the dealership do the first time? What did they write on the report?

How many miles on your car? Any engine mods?

 

Find out what they "fixed" the first time.
You might need to reset your ECU to retrain it.

They might not have fixed the first problem, really.

Do a search on this board about "MAP sensor" too.

Your thread topic certainly gave no hint as to what would be encountered.

You might try posting in "Under the Hood" if you don't get answers here.

 

my car is stock.. 19000 kms on it.
Funny thing is the dealer here in Dubai dont know anything about this car...
Mechanic told me the funniest thing when i did ask him for a report.. He said that he just Reset the car. Now what does that mean ..Even i couldnt tell.
Maybe they just reset the ECU. Well which one is the MAP sensor? I mean what does it look like?
