hesitating before boost

[davey red.r]

slight prob with my r ,runs fine when cold but when up to operating temps ,theres a hesitation before boost then ok on boost any ideas cheers davey;-)

Leads, fuel filter.........

Just look for the other missfire/hesitation threads, they're give you ideas of what to look at. ;-)

Could be running a bit rich at low revs.
Check air filter.

got my suspisions on that daft hks green mushroom carry on .as i know they can brake away. wouldnt it do it constantly tho if it was leads or filter? im drawn to a sensor being fawlty towers,shes in next week for a check up cheers davey

Not necessarily.
Both times when my fuel filter has been partially blocked, the miss fire/hesitation was very erratic !

the walbros only 6 month old, but you may be right ,thanks for the advice davey

my mistake thought you said fuel pump ,damn stellas:lol: :lol:

I'm a real ale guy myself... hickup.
Def' sounds like a fueling issue.
The reason I suspect rich running at low revs is that it's happy to run rich when cold but gasses up a bit when it's warm. If you have not changed the fuel filter after having changed your pump, it would do no harm to change it now.
I changed mine after a week of changing the fuel pump. I left it knowing that I would probably pick up some sh1t running so low on fuel then disturbing the crud when changing the pump....

disagree with all the above davey!
if the filter was partially blocked then it would not run freely on boost, when you require most fuel.
deffo sounds like a misfire prob to me so check all ignition components and do a code check!

fault code check, this may highlight issues such as det sensor, enjoyable little job really lol :lol:

Ant.
