Somebody help me with this, Boost related (ongoing :0()

Post by bidtowin »

Hello People

Just like to say great help so far with all the minimal problems i have had but i need a favour.

To cut a long story short, on boost my car sometimes does not boost or drive, i.e will not go past 3k, feels stuttery, this has only happened twice and each time it fixed itself.

Anyways recently the car has been running on lower boost, i.e the turbo feels weaker, this returns also to full boost the next day or next hour!, also on quarter throttle the car jerks a little, cuts in and out of boost, half/full throttle is fine.

Im pretty sure the 2 above problems are related, anyways have changed the plugs to a colder grade, checked the dizzy and rotor arm also and they are fine as well as the leads. Have also checked for errors and reset the ECU.

I really need some suggestions as this is all i need to do to make my 2 perfect. It feels like something is closing when it shouldnt be or opening.

Any ideas, suggestions, am thinking of changing my bleed valve to a G valve and maybe replacing the AFM or am i going down the wrong track?

Thanks

Ross

When was the last time you changed the plugs, leads, dizzy, rotor arm?

Ignition is one of the most important elements, and is the cause of poor running in alot of cases

go for some bigger leads, like magnecor kv85, get a new dizzy cap and rotor arm and some new plugs (denso iridium tipped ik 24) if this doesn't solve the problem then maybe the lord could help! :lol: :lol: if it don't work then at least uve ruled out ignition probs and got some top notch ignition bits for your 2. :) gud luck.

I have the same problems mate, but my car only bucks/stutters after I've been stuck in traffic then come on to boost, on a hot day or if I stop after a long drive and then start driving then come on to boost.

I've also changed the Dizzy Cap, Rotor Arm and fitted some Magnecor leads. :|
