Hello all you clever people
my car has started to have a slight hesitation when accelerating (random)
seems worse when i change up to 3rd
everything is lovely when going at speed
sometimes i get a little burble ? from the exhaust when pulling away in 1st
the car is serviced regularly and i only ever put shell petrol in
it starts fine every time and idles smoothly

any ideas thanks guys n gals

Dave

What you describe sounds like a misfire. Check the plugs leads and ignition coil if you can

Hi thanks for the reply
If it was a misfire surely it would miss slightly on idle
But mine idles smooth the needle does not move
Thanks again

Faulty leads and coils tend to play up under load so idling doesn't always cause a problem.
I'd do the leads first and go from there.

just an update it started to idle lumpy today so i thought sod it and got some new plugs ,leads and air filter
leads were a little longer than the old ones though ? but everything seems fine now
runs smooth no hesitation so fingers crossed I've done it and saved myself a few quid

thanks for your help people
