Recheck the timing on the dizzy as well. Should sort the 5000rev limit out. And give the throttle body a clean, should help with the pick up.

done anything to it recently ? new cap/rotor maybe >?

 

[davescupra]

yeah new cap rotor arm and plugs mate

air mass meter?

 

[Fl@pper]

still got the old ones handy >? try it with them or has it been an issue since before ?

reading the symptoms again sounds like the ignition coil to me or possibly an air leak somewhere

 

[davescupra]

it was a issue before mate,sorted that flat spot out i was gettin to much air i wrapped a towel around airfilter ,didnt come with standard airbox.i noticed its had a new coil.

 

[Fl@pper]

coils are very common fault mind.


if you have to wrap a towel around an air filter to get rid of a flat spot then surely you have an air leak somewhere ?

ill have a look mate
