running issues

[thewew]

hi my 1.4 16v corsa b seems to be a bit flat in acceleration i have changed the maf sensor and checked the vacum pipes but cant find any visable indication to tell me any faults it ideals fine and goes ok once its rolling thanks for all yoir help in advance

have you got a cone air filer on it? as these apparently cause them to lag a bit more, but for my car anyway the power doesnt kick in until 4,000rpm ish anyway, but then it does go all the way to the redline tho.

Bit more info wud be good tbh, wot do you mean abit flat?

when was the last time it had a good service?

[thewew]

yes mate i am running a green cotton cone filter it does need a service but i wouldnt of thought that would make a huge differance it just seems that when you put your foot down it doesnt seem to accelerate very quick with the revs

u wud be supprised the difference a service can make.

new oil and filter means the engine is proper lubricated and works alot more effecintly
new spark plugs means a better spark that will ignite the fuel faster
new fuel filter means cleaner fuel and it will move around more effecintly
etc.

and if its due one anyway theres no reason not to lol

ok cool i will give it a service and go from there cheers guys
