Poor Performance After Battery Change

[TriGem2k]

Its most likey that your ECU reset itself and is now back in its "learning" stage.

Drive it for 50-100 miles and it should be back to normal.

Also you need to reset the eGas.

With nothing touching the gas pedal, turn the ignition switch on (don't start the car).

Let it sit that way without touching the gas pedal for more than a minute (you will hear the throttle motor run).

Turn the ignition off for at least 10 seconds. Enjoy as usual.

Thanks for the feedback guys. I have reset the Egas a s suggested & driven now for over 180kms in a lively fashion, ie taking up to 7k on numerous occasions, & still the same issues remain.

Not sure what else to do.

it sounds like your MAF may be going bad. try unplugging it & go for a drive. if the drivability issues go away, you have found your problem.
