Missing When Changing Gear And Acceleration

[sravja01]

Hi, wonder if someone can help resolve my query.

My gal seems to miss in low revs and when changing gears (e.g. from 1st to 2nd and so on).

Noticed after Major Service.

Flushed engine, changed oil and filter, Slick engine additive, new air filter, new cabin filter, changed gear oil, new plugs, flushed radiator, changed aircon valve and re-gassed, fuel system cleaner, cleaned MAF, new belt, new water pump and replaced 2x tensioners. Even used high premium fuel.

Instead of impressive results - the car seems to misses when changing gears.

Has been on diagnostic machine but no faults.

Please can anyone help - spent over

You might want to add a little detail about the car, year/engine/gearbox etc

Ok there are loads of well informed peeps on here that can probably help but I think they are going to need a little more info:

 

Flushed engine? with what and how?

Slick engine additive? exactly what and how much?

New plugs? have these been removed and checked for correct gaps?

Fuel system cleaner? What type and how much and how applied?

Cleaned MAF? Although some reports of success are achieved by cleaning the most common approach is to replace.

2 x tensioners? There is only one on the cam belt, either the aux belt tensioner has been changed as well or you mean the idler pulley

Premium Fuel? Dont think this would have an effect but run the tank alost dry and then fill up with normal grade

 

Did you do the work yourself or was it done by a garage/dealer?

disconnect the MAF and see if there's any difference while driving.
