Sard New Member 23 Member For: 16y 3m 21d Posted 15/12/11 01:36 AM Share Posted 15/12/11 01:36 AM Hi all,I need help.My car drives normally up to about 3000 rpm. When it gets to there it misses badly and will not accelerate. When I back off there is a loud turbo flutter sound.I have done the following already:Replaced sparkplugs with IridiumsReplaced CoilsReplaced O2 SensorDid Boost Solenoid lube job (As shown on site)and last replaced Wastegate Actuator.Still doing it - this is getting very frustrating!Any ideas.

Sard New Member 23 Member For: 16y 3m 21d Posted 15/12/11 09:03 AM Author Share Posted 15/12/11 09:03 AM Thanks for your reply.Car is stock except centre muffler removed and KN Filter.Have done some stuff myself and some with a mechanic who do not seem to know what they are doing.So I have not seen the fault codes with my own eyes but they tell me there has been a code for spark (Did plugs and coils) then O2 sensor (I replaced it) and then actuator (They replaced it after I told them what it was and how to do it and I lubed the boost solenoid). Fuel filter has not been replaced recently - is it fuel but - wouldn't it play up most of the time not just at 3,000 RPm every time? Link to comment Share on other sites More sharing options...

Mr_4.0 Member 1,096 Member For: 14y 26d Posted 19/12/11 09:13 PM Share Posted 19/12/11 09:13 PM Yer I'd replace fuel filter. They are very cheap and easy to change. It might not be starving at low Revs but on boost could be very lean. Also those plugs you bought have a 1.1mm gap. You could try gently closing the gap to 0.8 aswell.
