Acceleration problem

[SilVectra]

Yep me again, sorry for the numerous posts.

My Vectra seems to go flat when accelerating, think its revs related.

when it gets to a certain point it seems to hold back.

I read somewhere about resetting the ECU by disconnecting the battery for 10 mins and then go for a long drive to recal the parameters

Is this correct and what sort of drive,, motorway or urban

Dont forget the airbox mod too,this sometimes give accerleration/hesitation problems,worth a try.......

Alot of us have done this and imo does improve accerleration/holding back problem that i had when i first got mine.....
