its not the same, when im not moving it seems to idle fine but if i just rest my foot on the gas slightly the revs go up and down up to 2 rpm to below 1 rpm, also it misfires and it kind of hesitates initially after each gear also feels as if its going to cut out when im setting off so i have to give it a more revs, mechanic checked dizzy, spark plugs and leads etc said they were fine although this was before i knew i had the new problem, he charged me £80 for getting the ignition coil and fitting it, i feel ripped off and dont have much money, so im asking you guys to see if you have any ideas before i take it back to the garage, had a mate look at it who said seems like it could be a breather pipe, but he did a check and couldnt find anything. cheers for any help!
